Dr. Thorsten Boroviak is an Assistant Professor at the University of Cambridge and a member of the Cambridge Stem Cell Institute. He discusses how stem cell–based embryo models are helping researchers study early human and primate development, including implantation and gastrulation. He also talks about using primate systems such as marmoset to understand human development, the role of biomechanics and extraembryonic tissues in embryogenesis, and the ethical considerations surrounding embryo models and emerging technologies like in vitro gametogenesis.

The Stem Cell Science Round Up

Mitophagy Controls Blood Stem Cells – Embryonic blood stem cells expand while staying multipotent thanks to tightly controlled ROS levels regulated by developmental mitophagy.

SLC4A3 Variants Drive Arrhythmia Risk – Mutations in SLC4A3 raise intracellular pH in heart cells, which shortens electrical signals and increases the risk of dangerous arrhythmias.

HSC Dynamics After Myeloablation – After chemotherapy, blood stem cells briefly boost differentiation to rebuild the blood system before returning to normal.

Modeling Duchenne Cardiomyopathy – Scientists generated heart organoids from Duchenne muscular dystrophy patient stem cells that mimic cardiomyopathy.
