Cause of ‘Down Syndrome’ cannot be pinned down to maternal age aloe

...e, have a relaxed stringency of quality control of embryos (or relaxed filtering stringency), which increases the probability that these women will bring children with developmental defects to full term. They believe that this relaxed filtering stringency is an adaptive maternal response and it might explai...

Are mature cells better than stem cells for cloning?

...lls destined to become granulocytes. Early stage embryos called blastocysts were generated from 35-39% of the mature granulocytes. However, only 4% of the immature stem cells could generate blastocysts. Two live cloned mice pups could be generated only by the differentiated granulocytes, though they died a...

Fertility Clinics Allowing Parents To Select Gender

...gnosis (PGD). This was initially intended to allow embryos to be screened for deadly genetic diseases. The technique takes a cell from a 3-day-old embryo and screens for presence of chromosomal abnormalities. The survey found that 186 out of 415 fertility clinics in the US were performing procedures to ident...

Roslin Cells Center Gives Fillip To Stem Cell Research

...onal Blood Transfusion Service. Donated eggs and embryos will form the basis of creation of human stem cells. These cells will be sold to stem research outfits and researchers. The pricing will be extremely soft, dictated by a non-profit motive. The center will be a hotbed for testing drugs and evolving ne...

Breakthrough In The Identity Of Compounds That Encourage Stem Cell Growth

... When stem cells isolated from the brains of mouse embryos were exposed to LTB4 they proliferated and differentiated, giving rise to additional stem cells and to differentiated neurons with limited or absent capacity to divide. When exposed to LXA4, these cells experienced decreased growth and apoptosis. "...

Scientists In UK Issue A Caution Over Untested Stem Cell Treatments

...nt kinds of tissue. The cells extracted from early embryos less than 14 days old can potentially be focussed to grow into any part of the body, from bones to brains. Scientists across the world are of the opinion that they will be used in future to develop new treatments for a host of diseases, including cur...
