Extensive Hair Shaft Growth after Mouse Whisker Follicle Isolation, Cryopreservation and Transplantation in Nude Mice.

Cao W, Li L, Tran B, Kajiura S, Amoh Y, Liu F, Hoffman RM - PLoS ONE (2015)

Bottom Line: DMSO better cryopreserved mouse whisker follicles compared to glycerol.Cryopreserved hair follicles also maintained the hair follicle-associated-pluripotent (HAP) stem cells, evidenced by P75NTR expression.Subcutaneous transplantation of DMSO-cryopreserved hair follicles in nude mice resulted in extensive hair fiber growth over 8 weeks, indicating the functional recovery of hair shaft growth of cryopreserved hair follicles.

ABSTRACT
We previously demonstrated that whole hair follicles could be cryopreserved to maintain their stem-cells differentation potential. In the present study, we demonstrated that cryopreserved mouse whisker hair follicles maintain their hair growth potential. DMSO better cryopreserved mouse whisker follicles compared to glycerol. Cryopreserved hair follicles also maintained the hair follicle-associated-pluripotent (HAP) stem cells, evidenced by P75NTR expression. Subcutaneous transplantation of DMSO-cryopreserved hair follicles in nude mice resulted in extensive hair fiber growth over 8 weeks, indicating the functional recovery of hair shaft growth of cryopreserved hair follicles.

pone.0145997.g005: Quantitative data of hair shaft growth in fresh and DMSO-cryopreserved hair follicles after hair follicle subcutaneous transplantation in nude mice.Each data point represents the 10 longest hair follicles for each group.

Mentions: In fresh hair follicles, the hair follicle established blood vessel connection with the host nude mice and grew rapidly by week 2 (1.26 mm ± 0.15mm). At week 4, the average of the 10 longest hair shafts length was 3.82 mm ± 0.31 mm. At week 6, the average of the 10 longest hair shafts length was 5.73 mm ± 0.31 mm), and at week 8, the hair shafts length was 7.66 mm ± 0.63 mm. The DSMO-cryopreserved hair follicle also established blood vessel connections with the host nude mice as indicated by red blood in the lower part and upper part of the hair follicle. At week 4, there were more blood vessels surrounding the hair follicles. There were obvious hair roots at the bulb area as well as longer hair shafts shaft at week 4, with the longest length of 1.88 mm ± 0.55 mm, compared to week 2, when the longest hair shaft length was 0.85 mm ± 0.07 mm (Fig 4). These results indicated that the DSMO-cryopreserved hair follicle started to rapidly regrow hair. At week 6, the longest hair shafts grew up to 2.85 mm ± 0.66 mm and more hair roots in the bulb area were observed, as well as long hair shafts growing out. Eventually, at week 8, there were a large amount of long hair shafts with the longest at a length of 4.92 mm ± 0.97 mm (Fig 5). Our results showed that DSMO-cryopreserved hair follicles maintained the ability to produce hair shafts after subcutaneous transplantation.
