Researchers Uncover Toggle Switch Guiding Stem Cell Fate in Olfactory Neurons

Cellular differentiation of stem cells into specialized cells requires many steps, including division, to create more cells; fate determination, which is a commitment to a specific lineage or developmental path; and migration, to integrate the cell into its final location.

New Cellular Mechanism Helps Cells Heal Faster

When cells are harmed, they produce well-regulated responses that promote healing. These include a long-studied self-destruction mechanism that eliminates dead and damaged cells, as well as a more recently discovered phenomenon that allows older cells to return to a younger state to aid in the regeneration of healthy tissue.

New "DNA Organizer" Found to Be Essential for Sperm Stem Cell Development

A research team at Kyoto University has discovered STAG3-cohesin, a new mitotic cohesin complex that helps establish the unique DNA architecture of spermaotogonial stem cells (SSCs), the stem cells that give rise to sperm.

Genetic Signatures of Neural Progenitor Cells Uncovered in the Adult Brain

For much of the 20th century it was thought that the adult brain was incapable of regeneration. This view has since shifted dramatically and neurogenesis – the birth of new neurons – is now a widely accepted phenomenon in the adult brain, offering promising avenues for treating many neurological conditions.
