Comparative Analysis of Somatic Stem Cells With Emphasis on Osteochondral Tissue Regeneration.

Congenital anomalies, diseases, and injuries may result in osteochondral damage. Recently, a big hope has been given to somatic stem cells (SSCs) which are characterized as undifferentiated cells with an ability of long-term self-renewing and plasticity. They are adherent with a fibroblast-like morphology in vitro and express various surface markers (e.

Stem Cells and Their Derivatives: An Implication for the Regeneration of Nonunion Fractures.

Despite advances in biomedical research, fracture nonunion rates have remained stable throughout the years. Long-bone fractures have a high likelihood of nonunion, but the specific biological pathways involved in this severe consequence are unknown. Fractures often heal in an organized sequence, including the production of a hematoma and an early stage of inflammation, the development of a soft callus and hard callus, and eventually the stage of bone remodeling.

A multimodal opioid-sparing pain management following total knee replacement.

Objective: The purpose of this study is to compare the pain scores, opioid consumption, and range of motion of the operated knee after total knee replacement (TKR) in the 10-day follow-up period between a traditional opioid-containing pain management protocol and a multimodal opioid-sparing treatment protocol.

Methods: This prospective, randomized, single-center study included 90 patients (24 men and 66 women; mean age 69.7±7.
