Engineered Cells Offer Promise for Treating ALS and Blinding Diseases

Engineered stem cells may lead to personalized treatments for a range of neurological and visual disorders, a new study reports. Transplanting engineered induced pluripotent stem cells into the eyes of rodents with retinal degeneration led to the protection of cells in the eyes that support vision. In ALS models, transplanting cells into the spinal cord protected movement controlling cells. The engineered cells also created astrocytes and did not result in tumor formation.

Fresh Questions About Oxytocin as the ‘Love Hormone’ Behind Pair Bonding

The "love hormone" oxytocin may not play as critical a role in bonding as previously believed. Removing the oxytocin receptor in animal models still resulted in monogamous mating, attachment, and parental bonding behaviors, although females without the receptor produced milk in smaller quantities. Findings reveal parenting and bonding aren't purely dictated by oxytocin receptors.
