The future of canine stem cell therapy: unprecedented, painless, and feeder-free      (via sciencedaily.com)     Original source 

Scientists have developed an efficient, non-invasive, and pain-free method to generate canine-induced pluripotent stem cells (iPSCs). They identified six reprogramming genes that can boost canine iPSC generation by 120 times compared to conventional methods using fibroblasts. The iPSCs were created from urine-derived cells without the need for feeder cells, an impossible feat until now. Their findings are expected to advance regenerative medicine and genetic disease research in veterinary medicine.

The key mechanism to cell growth has been elucidated      (via sciencedaily.com)     Original source 

Researchers have discovered how amino acids activate a key cell, TORC1, which is a master regulator in living organisms that controls whether cells grow or recycle their contents in yeast. Notably, the team found that the amino acid cysteine is sensed by a protein called Pib2 and that the two bind together to trigger TORC1. This is important because faulty TORC1 has been linked to disease such as cancer.

Bugs that help bugs: How environmental microbes boost fruit fly reproduction      (via sciencedaily.com)     Original source 

A research group found that in female fruit flies, microorganisms enhance reproductive function, boosting the number of cells that form eggs and the number of mature eggs. This is done by controlling the release of hormones to speed up cell division in the ovaries, and limiting programmed cell death. These findings could improve reproductive medicine and could aid the development of new methods to enhance fertility.

Cells of the future: A key to reprogramming cell identities      (via sciencedaily.com)     Original source 

The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just simply copying the genetic information; a well-orchestrated sequence of molecular events has to happen at the right time. Scientists have recently uncovered a fascinating aspect of this process known as 'replication timing' (RT) and how special this is when life commences.

New study examines the relationship between the rate of wound healing, the circadian rhythm, and 'hair' on cells      (via sciencedaily.com)     Original source 

Nearly every organism on Earth follows a natural circadian rhythm that is coded by your cell's clock genes, which do exactly as you suspect from the name: regulate your body's rhythm on a 24-hour basis. Most cells in mammalian bodies have cilia of some sort, which are hair-like structures that perform a variety of functions such as movement for motile cilia and aiding in structure in function for non-motile, or primary, cilia. The primary cilia also act as a sensory organ for the cell, a function which has illuminated the primary cilia's potential role in the healing process and how bodies heal at a different rate according to our circadian rhythm. In this research, the role of the primary cilia, biological clock and wound healing is explored.
