Pioneering stem cell procedure that doesn't just prevent hair loss but reverses it

Chris Wild, 39, from Enfield, North London, is one of the first people in Britain undergo a £2,000 pioneering stem cell procedure that doesn't just prevent hair loss but reverses it.

This study aimed to characterize the role of BDNF in age-related microglial activation. Initially, we found that degrees of microglial activation were especially evident in the substantia nigra (SN) across different brain regions of aged mice. The levels of BDNF and TrkB in microglia decreased with age and negatively correlated with their activation statuses in mice during aging. Interestingly, aging-related microglial activation could be reversed by chronic, subcutaneous perfusion of BDNF. Peripheral lipopolysaccharide (LPS) injection-induced microglial activation could be reduced by local supplement of BDNF, while shTrkB...

They go by different names: goosebumps, goose pimples, goose flesh, and my personal favorite, goose bumples. The medical term is cutis anserine (cutis means skin and anser means goose). I guess the similarity in texture is just too close to goose skin to ignore. Other medical terms for goosebumps are horripilation, piloerection, or the pilomotor reflex. Each of these terms describes a temporary change in the skin from smooth to bumpy, most commonly developing after exposure to cold. Many people associate goosebumps with fear, or perhaps more accurately, with horror. Perhaps that’s why a popular series of children&rsq...

In this study, we examined the effects of oxytocin on the Aβ-induced impairment of synaptic plasticity in mice. To investigate the effect of oxytocin on synaptic plasticity, we prepared acute hippocampal slices for extracellular recording and assessed long-term potentiation (LTP) with perfusion of the Aβ active fragment (Aβ25-35) in the absence and presence of oxytocin. We found that oxytocin reversed the impairment of LTP induced by Aβ25-35 perfusion in the mouse hippocampus. These effects were blocked by pretreatment with the selective oxytocin receptor antagonist L-368,899. Furthermore, the tr...

Researchers here analyze amounts and types of glycans in stem cells isolated from the skin of old and young mice. The differences observed might serve as a biomarker of aging, but also may be a contributing proximate cause of the age-related decline in skin stem cell function. As is usually the case, connecting downstream changes of this nature to the deeper causes of aging is a project yet to make any meaningful progress. It is also unclear as to whether glycan profile changes are a sizable cause of dysfunction versus all of the other possible proximate causes of stem cell functional decline. Aging in the epiderm...

The hairless (Hr) gene plays an essential role in hair follicle development and skin homeostasis. Both humans and mice lacking hairless activity suffer from complete hair loss and abnormal epidermal proliferation and differentiation, although the mechanisms underlying such developmental defects remain largely unknown. We recently demonstrated that Hr encodes a histone demethylase and acts as an epigenetic regulator of the expression of its target genes. Gene expression profiling studies identified pro-inflammatory IL-1 family cytokines, including IL-36 and IL-1 β, among the major targets of Hr.

Hair transplantation for the management of androgenetic alopecia is often limited by the number of donor HFs available for transplantation. Therefore, HF neogenesis technologies that enlarge the number of donor HFs are needed. Here, we assessed the potential of human primary adult hair matrix keratinocytes (HMx), i.e. the cells interacting with dermal papilla fibroblasts (DPs) in vivo, in generating HF organoids when co-cultured with DP spheroids in vitro and in human skin organ culture, compared to primary human adult epidermal keratinocytes (NHEK).

The follicular bulge is a stem cell niche where the outer root sheath (ORS) abuts the arrector pili muscle insertion site in both murine and human hair follicles. Prior studies have recognized an uncommon structure termed the “follicular trochanter” which was described as an epithelial protrusion of the outer root sheath in anagen follicles. It has been shown that these structures prominently express keratin 15, a stem cell marker. We sought to determine if trochanters embedded in the fibrotic stroma contribute to fo llicular scarring in cicatricial alopecias.

Conclusion: Taq-1 and Cdx-1 can be considered as risk factors for FPHL. They may play role in disease persistence rather than disease initiation. This association may be explained by failure of new anagen growth and decreased proliferation of hair follicle stem cells. Further studies are recommended to confirm current findings.

(Oregon Health&Science University) A new, hair-sprouting dollop of human skin created in the lab might one day help prevent hair loss. A paper published in Nature describes the hairy creation as the first hair-baring human skin organoid made with pluripotent stem cells, or the master cells present during early stages of embryonic development that later turn into specific cell types.
