Taming the genome's 'jumping' sequences

The human genome is fascinating. Once predicted to contain about a hundred thousand protein-coding genes, it now seems that the number is closer to twenty thousand, and maybe less. And although our genome is made up of about ...

How sperm stem cells maintain their numbers

The steady production of sperm relies on the number of sperm stem cells in the testis remaining constant. Researchers including Assistant Professor Yu Kitadate and Professor Shosei Yoshida (developmental biologists at the ...

Researchers glimpse elusive stem cell in the early embryo

Stem cell researchers at Harvard Medical School and Boston Children's Hospital have, for the first time, profiled a highly elusive kind of stem cell in the early embryo—a cell so fleeting that it makes its entrance and ...

Flow of cerebrospinal fluid regulates division

Stem cells in the brain can divide and mature into neurons participating in various brain functions, including memory. In a paper scientists have discovered that the flow of cerebrospinal fluid is a key signal for neural ...
