P.R.P., considered a nonsurgical treatment, is not covered by insurance, and clinical studies about its effectiveness (and longevity of results) are not conclusive because different doctors use different mixes. But P.R.P. has a long (though also inconclusive) history of use elsewhere in the body. Athletes like Kobe Bryant have received the treatment in an attempt to heal injuries.
Scientists from the Indiana University School of Medicine have for the first time created skin with hair follicles using mice stem cells. Research was led by Professor Karl Koehler. The team was able to grow both the epidermis and dermis layers of skin to create a realistic skin model. An interesting quote from Professor Koehler: “It looks like a little ball of pocket lint that floats around in the culture medium. The skin develops as a spherical cyst and then the hair follicles grow outward in all directions – like dandelion seeds.”
