Fighting Osteoporosis Through Cellular Signaling
December 19, 2022
A paper published in Experimental Gerontology has detailed how a bacterially derived compound may be useful in fighting osteoporosis. Osteoblasts and osteoclasts Osteoblasts are cells that build bone, and osteoclasts are cells that consume it. These two processes happen consistently and naturally in the human body.
