Sentences with phrase «tissue stem cells»

This general approach, known as lineage - tracing, has been a mainstay of classical developmental biology research and has greatly clarified knowledge of tissue stem cells during the last decade.

A novel mechanism — similar to how normal tissue stem cells respond to wounding — might explain why bladder cancer stem cells actively contribute to chemo - resistance after multiple cycles of chemotherapy drug treatment.

The researchers suggest that a single expandable embryonic lung progenitor population with broader developmental competence may eventually be used as an alternative for region - restricted adult tissue stem cells in regenerative medicine.

Connective tissue stem cells turn into fat (red) or bone (blue) depending on their starting shape.

«The cancer stem cells actively regrow and respond to the induced damage or apoptosis (cell death) caused by chemotherapy in between the different cycles, similar to how normal tissue stem cells respond to wound - induced damages.»

«We found that, contrary to popular belief, tissue stem cells derived from sick hearts do not contribute to heart healing after injury,» said Prof. Leor.

«We have developed a drug that acts like a vitamin for tissue stem cells, stimulating their ability to repair tissues more quickly.

Whether this recovery of tissue stem cell numbers is due to a replenishment of the stem cell pool from more differentiated cells, or due to an increase in «asymmetric» stem cell divisions that allow one stem cell to generate two new ones, remains to be answered, he said.

In normal cells, this is a part of the wound repair process when PGE2 induces tissues stem cells to regrow; in cancer PGE2 ironically induces regrowth of more cancer stem cells in between chemotherapy cycles, Kurtova and Xiao said.
