Hair Multiplication Study in Animal Model
“Formation of Hair Structures Suitable for Implantation” is the title of a newly published article from Intercytex. Hair multiplication, also known as hair cloning, has been discussed in our Hair Restoration Blog in many of our past posts and has been the subject of many studies in the past. Intercytex is one of the companies that have been reporting some progress in different levels of the study and have reported that they have finished phase II and are starting phase III of this study.
Their studies have shown that hair multiplication by hair culturing has been successful in animals and it is now being studied on humans. The following article tries to elucidate the process of hair multiplication on laboratory animals that have already been released.
The aim of the study was “to develop a construct through which implanted follicular cells will efficiently cause hair regeneration for the treatment of androgenetic alopecia.” They used follicular dermal and epidermal cells isolated from embryonic mouse skin which were formed into aggregates.
The aggregates were incubated in lab in culture for five to seven days and then implanted inside the skin into athymic mice, which does not have the capability of rejecting foreign tissue. They observed that during culturing, mixed cell aggregates developed into hair-like structures, termed “proto-hairs.” Proto-hairs contained structures that resembled normal hair components, such as dermal papillae, hair matrix and rudimentary hair shafts.
When implanted into mouse skin, they developed further into mature hair follicles capable of prolonged growth. The authors concluded that mixed aggregates of murine follicular cells have the ability to develop while in culture into proto-hairs that retain the ability to fully develop into hair follicles after implantation.
Proto-hairs from human hair stem cells could provide a convenient and practical means by which follicular cells could be implanted for efficient hair regeneration to treat hair loss. Although the study does not add to what we knew before, it elucidates the process of work for the other scientists who follow on the progress of hair multiplication (cloning) research.
We at US Hair Restoration California offices follow the progress of hair multiplication studies closely. We are also involved in some hair multiplication studies and the results will be released when completed.
