Stem cells and female reproduction: lessons from an unexpected source

Baltimore, MD. The recent findings reported in Nature (March 11, 2004) by Jonathon Tilly’s group at Harvard Medical School, show that female mice produce stem cells that give rise to eggs. This result overturns previous notions about mammalian reproduction, which held that females are born with all the eggs that they will ever have and that the decline in egg quality that occurs after a certain age is due to an extended aging process. What mammalian research has not been able to address at this point, however, is how these stem cells operate, what prompts them to develop into eggs, and why they are eventually lost. To answer these questions we must turn to our cousin the fruitfly.

Sleep apnea may be commonly misdiagnosed with hypertension

Patients with sleep apnea may be commonly misdiagnosed with hypertension, says a study published in the March issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians. In the study, one-third of patients with sleep apnea who were physician-diagnosed with hypertension actually had "white coat hypertension" (WCH), a condition characterized by an increase in blood pressure during a doctor's office visit and normal blood press during all other situations.
