Stem Cells Show Promise for Stroke Recovery; Early Study Found They Can Be Safely Transplanted into the Brain; 2 Patients Showed Significant ImprovementGoodman, Brenda
Scientists may have turned mouse skin cells into embryolike stem cells, but prior claims for the power of adult cells have yet to stand the test of time
But if you allow a beautiful jewelry watch to grow on you (like me), it will hit almost all the sweet spots: the weight of platinum with such visual quality. You won’t even notice its weight (Actually, you may be expecting and asking for it). And the proportions and modernity-al...
Over the course of a month, researchers expanded stem cells derived from the fat until there were more than 100 million cells. They then injected the cells into the patient’s spine in the lower back. Seven of the 10 patients improved as a result of the injections, resear...

Doctors hope that one day the body's master cells, called stem cells, can be directed to grow in organs or tissues appropriate for transplant, use them to test drugs and potentially toxic chemicals, and may study them to gain insight into basic human biology....
Initially, MSC success was thought to be through direct migration into affected tissues, where the stem cells would "transplant" themselves to occupy, differentiate, and thus repair damage. However,further studiesshowed that their action is paracrine. They secrete growth ...
Here, we demonstrate that naive hESCs can be converted into cells that exhibit the cellular and molecular phenotypes of human trophoblast stem cells (hTSCs) derived from human placenta or blastocyst. The resulting “transdifferentiated” hTSCs show reactivation of core placental genes, acquisition of...
Ptc is an antagonist of the Sonic hedgehog (Shh) signaling pathway, which functions as a critical regulator of both stem cells and progenitors in the central nervous system (Ahn and Joyner, 2005, Balordi and Fishell, 2007, Wechsler-Reya and Scott, 1999). Homozygous Ptc knockouts have ...
