A group of researcher from Walter and Eliza Hall Institute, Australia has got milestone in how the growth of milk producing mammary glands are triggered during the period of puberty. They have recently published it's paper today in journal of "Developmental cell"
According to published paper they discovered that sleeping stem cell in the mammary gland are awoken by FoxP1 Transcription factor.
Highlight of Fox1
- Fox p1 is transcription factor which is essential for mammary glands growth and development and it control the activation of quiescent MaSCs marked by Tspan8.
- Fox1 directly repressed the transcription of Tspan8 in basal but , not in luminal cells.
- Tspan8 deletion rescue the Foxp1 deficient mammary phenotype.
The researchers enlighten our knowledge of how the mammary gland stem cells are awoken by transcription factor and unplugged the better understanding of how defects in process lead to breast cancer.

The stem cell of mammary gland always exist in dormant state/ sleeping state through out the whole life span these stem cell need a signal to wake up to drive the fast and rapid increase in memory gland.
The mammary gland stem cell are ready for signal from transcription factor to start dividing she said "we discovered that a gene called foxp1 is an essential part of this signal in puberty and the adults" they discovered that fox p1 switched off the production of one of the key protein that keeps mammary stem cell wake up and begin to divide the growth and expansion of mammary glands.
This project is carried out in collaboration between scientist with diverse skills and brought together expertise on cell biology, developmental biology and imaging to solve the question of how memory stem cells are awoken in puberty and adults breast tissue.
