Study answers longstanding cell-development riddle

During the lifetime of a body—whether human, fish or any other type of vertebrate—cells die, making room for fresh new cells to carry on vital processes. The dead cells must be cleared away, though, and debris removal ...

Male germ cells can be directly converted into other cell types

Researchers have found a way to directly convert spermatogonial stem cells, the precursors of sperm cells, into tissues of the prostate, skin and uterus. Their approach, described this month in the journal Stem Cells, may ...

Histone modifications are the influencers of zygotic genome awakening

The zebrafish is an important model organism in biology. Humans and zebrafish share 70 percent of their genes, and more than 80 percent of human genes associated with disease are known to have a zebrafish counterpart. Additionally, ...

EU court: No patents for some stem cell techniques (Update 2)

The European Union's top court ruled Tuesday that scientists cannot patent stem cell techniques that use human embryos for research, a decision some scientists said could threaten major medical advances if it prevents biotech ...

S. Korea to revive stem cell research after scandal

President Lee Myung-Bak promised Monday to spend some $89 million restoring South Korea's reputation as a leader in stem cell research, five years after a scandal tarnished its reputation.

New insight into the regulation of stem cells and cancer cells

Scientists at the Gladstone Institutes have gained new insight into the delicate relationship between two proteins that, when out of balance, can prevent the normal development of stem cells in the heart and may also be important ...

'Landmark' study probes crucial phase of embryo development

An unprecedented glimpse of the human embryo at an early stage of development has provided critical clues on how undifferentiated cells become the specialized ones of which we are made, researchers reported on Wednesday.
