The chemical controlling life and death in hair follicles

2022-08-08 - 2022-08

A single chemical is a key to controlling when hair follicle cells divide, and when they die. This discovery could not only treat baldness but ultimately speed up wound healing because follicles are a source of stem cells. Most cells in the human body have a specific form and function determined during embryonic development that does not change. For example, a blood cell cannot turn into a nerve cell, or vice versa. Stem cells, however, are like the blank tiles in a game of Scrabble; they can turn into other types of cells.

New stem cell mechanism in your gut

Stem cells are a hot topic for creating medical treatments. However, scientists still do not fully understand how they choose to divide or differentiate to renew organs. Researchers have now found a new biophysical mechanism that regulates stem cells in the intestines of mice. There, a stem cell is not purely defined by intrinsic molecular markers but also by their location and movements in their environment. This could have implications for possible new treatments.

New patent-pending method mass-produces antitumor cells to treat blood diseases and cancer

A Purdue University chemical engineer has improved upon traditional methods to produce off-the-shelf human immune cells that show strong antitumor activity, according to a paper published in the peer-reviewed journal Cell Reports. Xiaoping Bao, a Purdue University assistant professor from the Davidson School of Chemical Engineering, said CAR-neutrophils, or chimeric antigen receptor neutrophils, and engraftable HSCs, or hematopoietic stem cells, are effective types of therapies for blood diseases and cancer. Neutrophils are the most abundant white cell blood type and effectively cross physiological barriers to infiltrate solid tumors. HSCs are specific progenitor cells that will replenish all blood lineages, including neutrophils, throughout life.
