Cathy Tie shared thisA thoughtful article by Sophia Ramirez at Columbia University - Graduate School of Journalism covering my recent debate with I. Glenn Cohen at the The Hastings Center for Bioethics. "Two Gene Editing Opponents Found They Agreed on Almost Everything." Despite being framed as a debate, we agreed on a central point: germline gene editing should ultimately be developed for patients. The discussion was not whether the technology should exist, but how, when, and for which diseases it should be used. The article closes with the perspective that matters most. After three years of IVF, a patient who lives with a hereditary cancer syndrome, said: "If Cathy tomorrow said 'Hey look, here's your embryos, we'll fix them,' I would take it." That is why these conversations matter. Thank you to Sophia Ramirez, the Hastings Center, and everyone who contributed to a thoughtful discussion on one of the most important biomedical questions of our time.

Cathy Tie shared thisA new preprint recently demonstrated multiplex adenine base editing in human embryos. Base editing is also one of the approaches we are using at Origin Genomics to study the correction of monogenic diseases caused by single-nucleotide variants. It's exciting to see the field continue to advance. Just a few years ago, embryo editing was largely discussed as a future possibility. Today, researchers are generating real data, testing increasingly sophisticated editing systems, and beginning to better understand the biological constraints involved. The paper demonstrates feasibility. The next frontier is improving efficiency, precision, and reproducibility through a deeper understanding of editor design, delivery, and developmental biology. https://lnkd.in/e66xpNKv

Cathy Tie reposted thisCathy Tie reposted thisTonight’s The Hastings Center for Bioethics panel on The Embryo Frontier: Editing Human Life was incredibly thought provoking. The discussion tackled one of the most complex questions in modern science: whether and how we should use gene editing in human embryos to prevent disease while navigating profound ethical implications. Beautifully moderated by Vardit Ravitsky, the conversation featured deeply engaging and nuanced perspectives from Cathy Tie and I. Glenn Cohen . A powerful example of how rigorous dialogue can elevate both science and society. #Bioethics is essential to biomedicine because it ensures that scientific and clinical advances respect human rights, promote fairness, and guide responsible decision-making. I look forward to more of these critical conversations! #geneediting

Cathy Tie shared thisFor my 30th birthday, I hosted an evening at Carnegie Hall dedicated to science and music, where I performed a Saint-Saëns piano concerto. The program also featured string ensemble, piano soloists, and opera performances. The evening was intended to support Canadian Sinfonietta and Cold Spring Harbor Laboratory, where I serve on the Association board. A highlight was immunology professor Peter Westcott performing Rachmaninoff, bringing both disciplines into the same space. I see philanthropy as a way to support institutions doing long-term, foundational work in the arts and sciences. Thank you to those who joined me for the evening.

Cathy Tie liked thisCathy Tie liked thisI would like to share my concern with a recent publication in Nature reporting a characterization of gene expression in a pre-gastrulation human embryo https://lnkd.in/eUSu6dq2. My concern is that this might not be a normal specimen and that by highlighting it in Nature it might become a misleading reference for an important field. Understanding early human development has been an important area of biology but access to early stages has been difficult. While the development of IVF ushered in ways of looking at preimplantation stages, the all important process of gastrulation has remained challenging due to the difficulty of obtaining specimens representative of the third and fourth weeks of development. The advent of postimplantation embryo culture and Stem Cell Based Embryo Models (SCBEMs) are filling this gap but they need benchmarking with data from human embryos. Given the current interest in gene cartography, the reference should be gene expression maps that complement the existing histology. The reference for human development is the collection of the Carnegie Institution and early development is divided into Carnegie Stages (CS). Important for this discussion are CS6 (d13, 14 pc) and CS7 d15-16. The publication reports a CS6 embryo with “no visible sign of primitive streak, primitive node or primitive groove, indicating a pre-gastrulation stage”. But then spatial transcriptomics reveals expression of genes associated with the node and others associated with later stages. I am extremely concerned to see this pattern in an embryo before the onset of the primitive streak, and surprised the authors do not show any concern. There are studies of gastrulation in different mammals and in none is there a report of the expression of these genes before the appearance of the primitive streak. It could be that human embryos are dramatically different to other mammals (I doubt it) but it could also be that this is an abnormal embryo (which I would favour). The problem is that it is going to be very difficult to cross-check these observations as it is not going to be easy to obtain another specimen at a similar stage. My concern is that this could be used as a benchmark for Human Embryos and that it will create confusion. In the wake of the observations, the discussion has a number of gratuitous references to the Spemann’s organizer that reveal deep ignorance of developmental biology the side of the authors. They seem to be happy to see gene expression of organizer genes without an organizer. This observation should be a cause of concern and not of celebration. My judgement could be wrong but, as they say, extraordinary claims require extraordinary evidence and I don’t see this here.Epiblast diversification and blood formation in a human pregastrula - NatureEpiblast diversification and blood formation in a human pregastrula - Nature

Or predict viral mutations before they happen? Or cut drug development from years to months? At the 90th CSHL Symposium on Quantitative Biology, those questions weren’t speculation, they were research talks.

Cathy Tie liked thisCathy Tie liked thisI attended the 90th Cold Spring Harbor Symposium on Quantitative Biology at Cold Spring Harbor Laboratory last week. AI x Bio 5 days. 50+ talks. One clear signal. Swipe through — 10 slides, one idea each. The highlights: → “AI is real. And there is a lot to get hung about.” (Bruce Stillman at the Opening) → CRISPR's clinical era has arrived (Jennifer Doudna – The Nobel Prize Laureate) → Scaling laws are now operating in biology (Alex Rives of Biohub) → The scientist's role is shifting from executing the how to defining the what (Pushmeet Kohli of Google DeepMind) → 362 agents. 30 days. 138 species. And radical candor about what AI still cannot do (Jonah Cool of Anthropic) → Four questions to ask before trusting any AI model in healthcare (Ewan Birney of European Bioinformatics Institute | EMBL-EBI) → Biology still outruns our machines in ways no one can fully explain (anthony zador of CSHL) The gap is closing fast. The open question is no longer whether AI can do Biology. It is whether we can prove it honestly and deploy it safely. The groups that pair bold models with rigorous validation will set the pace. The rest follow. XC CSHL Annual Symposium. Ninety and still mighty. A week like no other at a lab like no other! #AIinBiology #CSHL #CSHLSYMP26 #LifeSciences #DrugDiscovery #MachineLearning #Biotechnology

Post 3: What investors want to hear, and how to show it. After dozens of conversations in Boston (#RESI, #LSX) with investors and other biotech leaders, I'm using the following checklist with my team. The five proofs: 1. Proof of biology, clear MoA, human relevance, and a line of sight to clinical translation. 2. Proof of value, the payer story, who benefits, how much, and when, presented before Phase 2. 3. Proof of execution, a lean plan to the next inflection, with the right CROs and governance. 4. Proof of capital efficiency, budgets, options for non-dilutive finance, and the discipline to say no. 5. Proof of market access, credible BD optionality, including why your program is partnerable. Signals that build confidence: - A clean cap table and governance that can support a megaround if needed. This matches the prevailing market structure. - A realistic exit map, private M&A as the base case while IPOs are limited. Show who buys you, when, and for what evidence. - Awareness of global asset flows. Many large financings now back clinic ready assets, including programs sourced from China. Be ready to explain why your path to human data is similarly time efficient. - Discipline in public communication. Investors repeatedly say scarcity is an opportunity, for teams that prioritise and execute. I agree. Scarcity rewards focus. My closing view This environment is hard, and that is precisely why it is investable. Fewer companies will reach value inflections, the ones that do will be the ones that show the proofs above, and reach them with less spend.

The Licensing Boom in Chinese Biotech: A Glimpse Beneath the Surface On paper, the surge in Chinese biopharma licensing deals in 2025 looks like a revival. In the first half of the year alone, Chinese companies signed over 48.5 billion dollars in outbound licensing agreements. That figure already surpasses the full-year total for 2024. Read the full article: https://lnkd.in/eRwV-D5Q Western pharmaceutical firms, under pressure to replenish pipelines, are increasingly turning to Chinese partners for oncology and immunology assets. Takeda, GSK, Pfizer, and others have inked landmark agreements. The scale of these deals suggests confidence, capital, and clinical depth. But that is the foreground. What lies behind it is more revealing. The rush of licensing activity is in large part a response to a weakened domestic venture capital environment. Since the 2021 peak, VC funding for Chinese biotech has contracted sharply. Foreign investors have pulled back due to capital controls and geopolitical pressure. Domestic VC funds are more cautious, often steered by policy mandates into industrial technologies. As a result, private biotech companies face a capital bottleneck. Licensing deals offer a workaround. By out-licensing global rights to promising molecules, Chinese firms can unlock large upfront payments and near-term milestones. These cash infusions are, for many, the only viable alternative to growth-stage equity. The deals are large, sometimes reaching billions in total potential value, but they are also defensive. They reflect an ecosystem adapting to capital scarcity rather than one experiencing investment exuberance. This shift has not gone unnoticed. Royalty investors such as Royalty Pharma have become more active in evaluating Chinese assets. Their model, exchanging present capital for a future stream of milestones or royalties, fits perfectly into this environment. For royalty buyers, China now offers a pipeline of discounted cash flows at attractive entry points. For Chinese developers, it provides another avenue to monetize long-tail agreements that might otherwise remain illiquid. The model is financially rational. It allows innovation to proceed, partnerships to deepen, and pipelines to advance. But it also externalizes upside. Chinese companies are increasingly funding innovation by selling the future. While that provides runway today, it could constrain independence and value capture tomorrow. Moreover, regulatory risks remain. Policymakers in the US are beginning to scrutinize biopharma cooperation with China, and any shift in that posture could chill this licensing flow.
