Study reveals key protein that helps prevent excessive bone loss in osteop
Updated : 1 year, 9 months ago IST
Osteoporosis, a disorder characterised by porous and weak bones, is a major hazard to skeletal health. As the foundation of the human body, bones provide critical structural support. When bone mass decreases, it not only weakens this support but also lowers general function, resulting in a l

Stem cells role in protecting gastric mucosa, finds study
Updated : 2 years, 8 months ago IST
The parietal, chief, pit, and neck cells make up the gastric corpus, which is a major component of the glandular stomach. Each of these specialised epithelial cells plays a crucial part in digestion, and they are constantly replenished by new ones created by stem cell differentiation. Gastri

Study finds how worm embryos produce specific, pluripotent cells
Updated : 2 years, 11 months ago IST
Researchers have discovered how specific proteins within roundworm chromosomes enable their offspring to produce specialised cells generations later, a startling discovery that challenges the conventional wisdom that hereditary information for cell differentiation is primarily ingrained with

Scientists identify vital mechanisms controlling skin regeneration
Updated : 2 years, 4 months ago IST
The outer layer of skin, the epidermis, is constantly turning over to replace dead or damaged cells throughout our lifetime. Skin stem cells need to continuously make decisions: either make more copies of themselves (self-renewal) or switch their fate towards differentiation. The molecular m

Researchers find macrophages may be scavenger cells of the immune system
Updated : 3 years, 6 months ago IST
Washington [US], September 17 (ANI): Alveoli are microscopic air sacs in our lungs that exchange gases between the air we breathe and our blood. To keep this process running properly, the alveolar epithelial cells create a material called "surfactant," which coats the alveoli like a film. Th

Scientists demonstrate how injuries are converted to regeneration signals
Updated : 3 years, 6 months ago IST
Washington [US], September 5 (ANI): The phenomenon of regeneration was discovered over 200 years ago in the freshwater polyp Hydra. Until now, however, it was largely unclear how the orderly regeneration of lost tissues or organs is activated after injury. In its investigations of Hydra, an
