New ULCA stem cell research show promise

Examiner | Robin Wolffsom, MD

UCLA stem cell researchers are one step closer to growing new organs (i.e., hearts, livers, and kidneys) and regenerating tissue from tissues damaged by diseases such as arthritis or osteoporosis. New tissue is formed by the division of existing cells. The UCLA researchers have discovered a process known as left-right asymmetry, which occurs when cells divide. They have found that migrating cells prefer to turn right when they encounter a change in their environment. The researchers were able to recreate this left-right asymmetry on an early tissue level. This process is important for the creation of differences between the right and left sides of structures such as the brain or hand, which has a thumb on one side and a little finger on the other. The results of the study were published in the February 17 edition of the journal Circulation Research.
