Advances in tissue engineering led to the development of various tissue-engineered skin substitutes (TESS) for the treatment of skin injuries. The majority of the autologous TESS required lengthy and costly cell expansion process to fabricate. In this study, we determine the possibility of using a low density of human skin cells suspended in platelet-rich plasma (PRP)-enriched medium to promote the healing of full-thickness skin wounds. To achieve this, full-thickness wounds of size 1.767 cm(2) were created at the dorsum part of nude mice and treated with keratinocytes (2 × 10(4) cells/cm(2)) and fibroblasts (3 × 10(4) cells/cm(2)) suspended in 10% PRP-enriched medium...

Facial scaring is considered one of the most difficult cosmetic problems for any plastic surgeon to solve. The condition is more difficult if the direction of the scar is not parallel to relaxed skin tension lines. Attempts to manage this difficult situation included revisions using geometric designs, Z plasties or W plasties to camouflage the straight line visible scaring. The use of long-lasting resorbable sutures was tried too. Recently, the use of botulinum toxin during revision improved the results. Fractional CO2 lasers, microfat grafts, and platelet-rich plasma were added to the armamentarium...

BACKGROUND: Tissue expansion has been widely applied in clinic practice. However, the expanded skin is always insufficient for clinical use and how to promote tissue expansion is still a challenge. Platelet-rich plasma (PRP) contains multiple tissue growth factors and has been widely utilized in hard- and soft-tissue augmentation. However, its feasibility to promote tissue expansion has not been explored. The purpose of this study was to evaluate the possible effect of PRP in tissue expansion...

Chronic wounds affect over 4 million individuals and pose a significant burden to the US healthcare system. Diabetes, venous stasis, radiation or paralysis are common risk factors for chronic wounds. Unfortunately, the current standard of care (SOC) has a high relapse rate and these wounds continue to adversely affect patients' quality of life. Fortunately, advances in tissue engineering have allowed for the development of cell-based wound dressings that promote wound healing by improving cell migration and differentiation...

BACKGROUND: Lichen sclerosus (LS) is an inflammatory dermatosis with autoimmune pathogenesis. Although relatively common, its true incidence is unknown and likely underestimated. LS is usually anogenital, but in around 10% of patients, it can present as extragenital lesions. Continuous administration of topical corticosteroids is the mainstay of medical treatment. Other treatments are available but are only occasionally prescribed along with or instead of topical steroids. Injection of platelet-rich plasma (PRP) into affected areas has been reported to result in the regeneration of normal skin...

Mesenchymal stromal cells (MSCs) play a pivotal role in modern therapeutic approaches in bone-healing disorders. Although bone marrow-derived MSCs are most frequently used, the knowledge that many other adult tissues represent promising sources for potent MSCs has gained acceptance. In the present study, the osteogenic differentiation potential of porcine skin fibroblasts (FBs), as well as bone marrow- (BMSCs), adipose tissue- (ASCs) and dental pulp-derived stromal cells (DSCs) were evaluated. However, additional application of BMP-2 significantly elevated the delayed osteogenic differentiation capacity of ASC and FB cultures, and in DSC cultures the supplementation of platelet-rich plasma increased osteogenic differentiation potential to a comparable level of the good differentiable BMSCs...
