Abstract
BACKGROUND Exosomes are small extracellular vesicles that play important roles in intercellular communication and have potential therapeutic applications in regenerative medicine. Dermal mesenchymal stem cells (DMSCs) are a promising source of exosomes due to their regenerative and immunomodulatory properties. However, the molecular mechanisms regulating exosome secretion from DMSCs are not fully understood. RESULTS In this study, the role of peroxiredoxin II (Prx II) in regulating exosome secretion from DMSCs and the underlying molecular mechanisms were investigated. It was discovered that depletion of Prx II led to a significant reduction in exosome secretion from DMSCs and an increase in the number of intracellular multivesicular bodies (MVBs), which serve as precursors of exosomes. Mechanistically, Prx II regulates the ISGylation switch that controls MVB degradation and impairs exosome secretion. Specifically, Prx II depletion decreased JNK activity, reduced the expression of the transcription inhibitor Foxo1, and promoted miR-221 expression. Increased miR-221 expression inhibited the STAT signaling pathway, thus downregulating the expression of ISGylation-related genes involved in MVB degradation. Together, these results identify Prx II as a critical regulator of exosome secretion from DMSCs through the ISGylation signaling pathway. CONCLUSIONS Our findings provide important insights into the molecular mechanisms regulating exosome secretion from DMSCs and highlight the critical role of Prx II in controlling the ISGylation switch that regulates DMSC-exosome secretion. This study has significant implications for developing new therapeutic strategies in regenerative medicine. Video Abstract.

Abstract
BACKGROUND Psoriasis is a chronic inflammatory skin disease characterized by excessive proliferation and abnormal differentiation of keratinocytes. Dermal mesenchymal stem cells (DMSCs) are not only involved in the regeneration of skin tissue, but also can regulate skin microenvironment by secreting cytokines. However, whether and how psoriatic DMSCs regulate proliferation and differentiation of keratinocytes remains unknown. OBJECTIVE To study the effects of psoriatic DMSCs on the proliferation, differentiation, and migration of keratinocytes and the underlying mechanisms. METHODS Following co-cultures of HaCaT cells with either psoriatic DMSCs (p-DMSCs) or DMSCs from normal volunteers (n-DMSCs), HaCaT cell proliferation was assessed using CCK-8 and EDU incorporation assay, while scratch assay and transwell assay were used to assess cell migration. qRT-PCR was used to determine expression levels of mRNA for cell proliferation (Ki-67) and differentiation (keratin 5, involucrin, and filaggrin). Western blot was used to measure expression levels of proteins associated with keratinocyte proliferation and differentiation in cultured HaCaT cells treated with or without PI3K inhibitor. ELISA assay was used to measure expression profile of stem cell factor (SCF), epidermal growth factor (EGF), and interleukin-11 (IL-11) within the co-culture supernatants. RESULTS The results showed that p-DMSCs displayed a higher potency than n-DMSCs in stimulating proliferation, differentiation, and migration of HaCaT cells. Expression levels of PI3K and AKT proteins were markedly increased in HaCaT cells co-cultured with DMSCs versus HaCaT cell culture alone. Moreover, inhibition of the PI3K/AKT signaling pathway reversed the effect of p-DMSCs on proliferation, differentiation, and migration of HaCaT cells. Compared with n-DMSCs, the p-DMSCs showed increased secretion of IL-11, EGF, and SCF. CONCLUSION p-DMSCs stimulate HaCaT cell proliferation, differentiation and migration via activating the PI3K/AKT signaling pathway, providing a new insight into the pathogenesis of psoriasis.

Abstract
OBJECTIVE To investigate the regulation of psoriatic dermal mesenchymal stem cells (p-DMSCs) in the expression of vascular growth factor (VEGF), and migration and angiogenesis of human umbilical vein endothelial cells (HUVECs) in vitro. METHODS A co-culture model of HUVECs and dermal mesenchymal stem cells (DMSCs)was used in this study. After 7-day co-culture, changes in expression levels of VEGF mRNA and protein in HUVECs were assessed using RT-PCR and Western Blotting, respectively. Migration and tubular formation of HUVECs were also assessed following co-culture of DMSCs and HUVECs. RESULTS In comparison to either HUVECs alone or co-culture of n-DMSCs and HUVECs, co-culture of HUVECs and p-DMSCs significantly increased expression levels of both VEGF mRNA (p < 0.01 vs. HUVECs alone) and protein in HUVECs (p < 0.001 vs. both HUVECs alone and HUVECs co-cultured with n-DMSCs). Moreover, p-DMSCs stimulated HUVEC migration and vascular formation (p < 0.05 vs. both HUVECs alone and co-culture of n-DMSCs and HUVECs). CONCLUSION Psoriatic DMSCs can upregulate VEGF expression, and stimulate migration and angiogenesis of HUVECs, suggesting a pathogenic role of p-DMSCs in psoriasis.

Abstract
Dermal mesenchymal stem cells (DMSCs) are progenitor cells with the capacity of self-renewal, multilineage differentiation, and immunomodulation, which were reported to induce the proliferation of keratinocytes, however the regulation on keratinocytes apoptosis was unknown. In this study, we isolated DMSCs from normal skin and co-cultured with keratinocytes, and then detected apoptosis of keratinocytes by flow cytometry and expression of apoptosis associated proteins by western blot. The mRNA expression profile of normal DMSCs was investigated by RNA sequencing. The results of our study presented that the DMSCs promoted HaCaT cells apoptosis both in early apoptotic state (13.8 vs. 2.9, p < 0.05) and late apoptotic state (4.2 vs. 0.7, p < 0.05). The expression of apoptosis associated proteins caspase-3 (3.51 vs. 1.99, p < 0.05) and lymphoid enhancer-binding factor 1 (3.10 vs. 0.83, p < 0.05) were upregulated. However, the cell cycle protein cyclin E1 was similar (9.38 vs. 9.05, p > 0.05). Moreover, 33 genes with the function of induced cell apoptosis were highly expressed in DMSCs, including insulin-like growth factor-binding protein 4 (2828.13), IGFBP7 (1805.69), cathepsin D (1694.34), cathepsin B (CTSB, 1641.40) and dickkopf WNT signaling pathway inhibitor 1 (DKK1, 384.79). This study suggested DMSCs induce the apoptosis of keratinocytes through non-G1/S phase blockade via highly expression of apoptosis inducer.

Abstract
The dermal mesenchymal stem cells (DMSCs) from psoriasis display higher expression level of epidermal growth factor-like repeats and discoidin I-like domains 3 (EDIL3), while EDIL3 can bind integrins, including αvβ3 and αvβ5, to regulate angiogenesis. To assess the role of EDIL3 derived from DMSCs of psoriasis (P-DMSCs) in angiogenesis, in vitro, EDIL3 of DMSCs from psoriasis was silenced by interfering EDIL3. Then the efficacy of silencing EDIL3 was tested by fluorescent flag, qRT-PCR and western blotting. And, in vitro, the relationship of EDIL3 in DMSCs with the angiogenesis of HUVECs were investigated through co-culture system. In vivo, EDIL3 recombinant protein was injected into IMQ cream-induced psoriasis-like skin lesions of mouse and EDIL3-associated tube formation were determined using Image J software. Our results showed the capacity of the adhesion, migration and tube formation of HUVECs in all psoriatic DMSCs groups were significantly higher compared with the control and si-EDIL3 groups (all P<0.05) in vitro. Moreover, under stimulated by EDIL3 recombinant protein, EDIL3-associated tube formation was dramatically elevated in vivo (P<0.01). In this study, EDIL3 could promote the adhesion, migration and tube formation of ECs and participant in the angiogenesis pathogenesis of psoriasis through affecting biological function on ECs both in vitro and in vivo. The results suggest a potential role of the critical pro-angiogenic factor EDIL3 in psoriasis therapy.

Abstract
Both skin-derived precursors (SKPs) and dermal mesenchymal stem cells (dMSCs) are promising candidates for cellular therapy and regenerative medicine. To date the comparison of phenotypes and transcriptomes of mouse SKPs (mSKPs) and dMSCs has never been reported. Here we characterized and compared the biological properties and transcriptomes of mSKP and dMSCs from the same mouse dermis sample. Firstly, we analyzed mSKPs and dMSCs by use of immunocytochemistry, cell cycle analysis, and CD antigen expression. Then we conducted the osteogenic, adipogenic, and chondrogenic induced differentiation for both cell types. Lastly, we compared their genomic profiles by RNA-sequencing (RNA-Seq), and verified the results of RNA-Seq by quantitative real time reverse transcription PCR (qRT-PCR). The results suggested that mSKPs and dMSCs shared similarities in certain positive stem cells markers expression, but demonstrated difference in Nanog and Oct4 expression. mSKPs and dMSCs demonstrated similar cell cycle distribution and CD antigen expression. Both types of cells could be induced differentiated into osteocytes, adipocytes, and chondrocytes. However, RNA-Seq and qRT-PCR results indicated that mSKPs and dMSCs had distinct transcriptome profiles. The majority of enriched differentially expressed genes (DEGs) from mSKPs was immune-related, while the majority of enriched DEGs from dMSCs was differentiation/development/disease-related. Transcriptome profiles suggested that mSKPs and dMSCs might have potential usage in the relevant morbidity management. These results may indicate a molecular basis for novel stem cell-based therapeutic strategies.

Abstract
Mesenchymal stem cells (MSCs) are used for tissue regeneration in several pathological conditions, including autoimmune diseases. However, the optimal sources and culture requirements for these cells are still under investigation. Here, we compared mRNA expression in dermal MSCs (DMSCs) at passage (P) 3 and P5 to provide a reference for future studies related to DMSCs expansion. In normal DMSCs, the expression of three of eight genes associated with basic cellular activity were different at P5 compared to that at P3: PLCB4 and SYTL2 were upregulated by 4.30- and 6.42-fold, respectively (P < 0.05), whereas SATB2 was downregulated by 39.25-fold (P < 0.05). At the same time, genes associated with proliferation, differentiation, inflammation, and apoptosis were expressed at similar levels at P3 and P5 (P > 0.05). In contrast, in DMSCs isolated from psoriatic patients we observed differential expression of three inflammation-associated genes at P5 compared to P3; thus IL6, IL8, and CXCL6 mRNA levels were upregulated by 16.02-, 31.15-, and 15.04-fold, respectively. Our results indicate that normal and psoriatic DMSCs showed different expression patterns for genes related to inflammation and basic cell activity at P3 and P5, whereas those for genes linked to proliferation, differentiation, and apoptosis were mostly similar.
