Abstract
Androgenetic alopecia (AGA), also known as male pattern baldness, is a common hair loss condition influenced by genetic and hormonal factors. Variations in gene expression and androgen responsiveness have been observed between the frontal and occipital regions of AGA patients. However, obtaining and cultivating frontal hair follicles is challenging. Therefore, no matched frontal and occipital dermal papilla (DP) cell lines have been reported yet. This study aimed to establish matched immortalized human frontal and occipital scalp DP cell lines from AGA patients. Simian virus 40 large T antigen (SV40T-Ag) and human telomerase reverse transcriptase (hTERT) were introduced into primary human DP cells. The obtained cell lines were characterized by assessing their gene expression patterns, androgen receptor (AR) levels, and the presence of 5-alpha reductase (5αR). Additionally, we examined their response to dihydrotestosterone (DHT) and evaluated cell viability. The conditioned medium from the frontal DP cell line inhibited human hair follicle growth, leading to reduced keratinocyte proliferation and increased apoptosis. Furthermore, when the cells were cultured in a 3D environment mimicking in vivo conditions, the 3D cultured frontal DP cell line exhibited weaker sphere aggregation than the occipital DP cell line due to the increased expression of matrix metalloproteinase 1 (MMP1), MMP3, and MMP9. Additionally, the expression of DP signature genes was inhibited in the 3D cultured frontal DP cell line. These matched frontal and occipital DP cell lines hold significant potential as valuable resources for research on hair loss. Their establishment allows us to investigate the differences between frontal and occipital DP cells, contributing to a better understanding of the molecular mechanisms underlying AGA. Furthermore, these cell lines may be valuable for developing targeted therapeutic approaches for hair loss conditions.

Abstract
Stress can be one of the leading causes of hair loss. Stress related hormones, glucocorticoids (GCs), secretion by hair follicle have been mentioned in literature and proven to exert an inhibitory effect on hair follicle cells growth by modulating the expression of target genes related to cell proliferation and cycling. The gene modulating effect of the synthetic GC, dexamethasone (DEX), in human dermal papilla (DP) cells has been outlined in this study by mediating a contradictory effect on the expression of secreted frizzled related protein 2 (SFRP2) and SFRP3. The SFRP2 and SFRP3 possess a regulating effect on wnt signaling pathway. Their structural similarities to the cysteine-rich-domain of the frizzled receptors (FZD) allow their binding to the wnt ligands causing the blocking of the wnt ligands-receptors complex. The SFRP family members have been known as inhibitors of the wnt signaling modulating the proliferation and development of various cells. In hair follicle cells, SFRP2 activity has been reported positively on the proliferation of keratinocytes. However, the SFRP3 effect hasn't been well addressed. Under stress, the investigation of the mRNA and protein expressions of SFRP members in human DP cells revealed opposite expressions where SFRP2 decreased while SFRP3 increased by DEX. The proliferation rate of hair keratinocytes outer root sheath was detected via immunofluorescence highlighting the stimulatory effect of SFRP2 and the inhibitory effect of SFRP3. Here, we sought to determine the effect of GC agonist on SFRPs expression and their effect on hair follicle growth.

Abstract
Psychosocial stress stimulates the secretion of glucocorticoids (GCs), which are stress-related neurohormones. GCs are secreted from hair follicles and promote hair follicle regression by inducing cellular apoptosis. Moreover, the androgen receptor (AR) is abundant in the balding scalp and androgens suppress hair growth by binding to androgen receptor (AR) in androgenetic alopecia (AGA). First, by using immunofluorescence, we investigated whether the treatment of dermal papilla (DP) cells with dexamethasone (DEX), a synthetic GC, causes the translocation of the glucocorticoid receptor (GR) into the nucleus. DEX treatment causes the translocation of the GR into the nucleus. Next, we investigated whether stress-induced GCs affect the AR, a key factor in male pattern baldness. In this study, we first assessed that DEX increases the expression of AR mRNA in non-balding DP cells, which rarely express AR without androgen. RU486, a GR antagonist, attenuated DEX-inducible AR mRNA expression and AR activation in human non-balding DP cells. In addition, AR translocated into the nucleus after DEX treatment. Furthermore, we indeed showed that the expression of AR was induced in the nucleus by DEX in DP cells of human and mouse hair follicles.
Our results first suggest that stress-associated hair loss may be due to increased AR expression and activity induced by DEX. These results demonstrate that hair loss occurs in non-balding scalps with low AR expression
