Peripheral nerve injuries are common complications in surgical and dental practices, often resulting in functional deficiencies and reduced quality of life. Current treatment choices, such as autografts, have limitations, including donor site morbidity and suboptimal outcomes. Adipose-derived stem cells (ADSCs) have shown assuring regenerative potential due to their accessibility, ease of harvesting and propagation, and multipotent properties. This review investigates the therapeutic potential of ADSCs in peripheral nerve regeneration, focusing on their use in bioengineered nerve conduits and supportive microenvironments. The analysis is constructed on published case reports, organized reviews, and clinical trials from Phase I to Phase III that investigate ADSCs in managing nerve injuries, emphasizing both peripheral and orofacial applications. The findings highlight the advantages of ADSCs in promoting nerve regeneration, including their secretion of angiogenic and neurotrophic factors, support for cellular persistence, and supplementing scaffold-based tissue repair. The regenerative capabilities of ADSCs in peripheral nerve injuries offer a novel approach to augmenting nerve repair and functional recovery. The accessibility of adipose tissue and the minimally invasive nature of ADSC harvesting further encourage its prospective application as an autologous cell source in regenerative medicine. Future research is needed to ascertain standardized protocols and optimize clinical outcomes, paving the way for ADSCs to become a mainstay in nerve regeneration.

To provide protection, anticipatory T cell-dependent immunity is reliant on the generation and maintenance of a naïve T cell repertoire, which is sufficiently diverse to ensure recognition of newly encountered antigens. Therefore, under steady-state conditions, a given individual needs to maintain a large pool of naïve T cells, ready to respond to potential threats. Here, we demonstrate that N-myc downstream-regulated gene 3 (Ndrg3) is essential for naïve T cell stability.

As arthroscopic and open shoulder surgery is increasingly performed on an outpatient basis, optimal and prolonged pain control is becoming more important while minimizing associated adverse effects. Traditional analgesic strategies relying on opioid and nonopioid medications provide inadequate pain control and are associated with undesirable adverse effects, such as opioid-related adverse effects (postoperative nausea and vomiting, respiratory depression, sedation), gastric lining irritation, and renal and hepatic adverse effects. Advances in ultrasonography-guided regional anesthesia have made placement of interscalene brachial plexus nerve blocks more reliable and precise and aided development of novel phrenic nerve-sparing peripheral nerve block techniques that decrease the risk of diaphragmatic paresis and dyspnea.

A significant portion of adolescents suffer from mental illnesses and persistent pain due to repeated stress. The components of the nervous system that link stress and pain in early life remain unclear. Prior studies in adult mice implicated the innate immune system, specifically Toll-like receptors (TLRs), as critical for inducing long-term anxiety and pain-like behaviors in social defeat stress (SDS) models.

Peripheral nerve tissue engineering is a field that uses cells, growth factors and biological scaffold material to provide a nutritional and physical support in the repair of nerve injuries. The specific properties of injectable human amniotic membrane-derived hydrogel including growth factors as well as anti-inflammatory and neuroprotective agents make it an ideal tool for nerve tissue repair, and metformin may also aid in nerve regeneration. The aim of this study was to investigate the effects of hydrogel derived from amniotic membrane (AM) along with metformin (MET) administration in the repair of sciatic nerve injury in male rats.

Despite its contributions, postamputation pain remains a significant problem. This study aims to investigate the role of sciatic nerve regenerative peripheral nerve interface (RPNI) in patients undergoing transfemoral OI, focusing on its impact on pain and prosthetic wear.
