This study found that women with polycystic ovary syndrome had significantly higher serum lactate dehydrogenase levels and lower levels of cortisol, dopamine, zinc, and vitamin D3 compared to healthy controls.

In this study, researchers found that alopecia areata is linked to immune cell activation against hair follicle autoantigens and is associated with heart changes and cardiac marker alterations in humans and mice.

This article reviews the potential advantages of secretome derivatives from human uterine cervical stem cells in MSC therapy and notes the need for regulatory standards to ensure safety and efficacy.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

This review discusses the role of stem cell progeny as integral components of stem cell niches, offering feedback that may influence different stem cell systems' microenvironments, but it presents no new research findings.

This review discusses the role of regulatory T-cells in tissue repair and regeneration across various organs and reports no new clinical results.

This review discusses various therapeutic strategies targeting platelet-derived growth factor signaling in diseases like cancer and atherosclerosis, and evaluates existing treatments without presenting new clinical data.

This review summarizes recent advances in Treg cell biology, focusing on Foxp3's role in immune regulation and therapeutic reprogramming for immune dysregulatory disorders, but reports no new clinical results.

In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

This study found no evidence supporting the hypothesis that Aβ afferents sprout into the superficial laminas of the spinal cord after nerve injury in rats.

This review discusses strategies for regenerating cutaneous nerve function in burn patients and highlights the potential role of autologous skin-derived adult stem cells in improving sensory recovery, but reports no new experimental findings.

This article discusses recent advances in understanding the mechanisms of tactile end organs in the epidermis and hair follicles from studies of mouse hairy skin, but it reports no new clinical results.

This study observed that androgenic alopecia patients taking finasteride had altered neuroactive steroid levels and persistent depression symptoms even after stopping the treatment.

This review discusses the advancements and challenges in developing in vitro human skin models incorporating components like vasculature for drug testing and disease research, but reports no new clinical results.
