This study was to explore curative effect of bone marrow stromal cells (BMSCs) differentiated into nestin-positive cells transplantation on rat Parkinson's disease (PD) model. The PD rats were selected and allocated randomly into three groups. BMSCs with differentiation, BMSCs without differentiation and physiological saline were injected into right striatum of PD rat. The rotation test and immunofluorescence double staining were done. Frequency of rotation was significantly less in differentiated or non-differentiated BMSCs groups than that in normal saline group. Brdu/GFAP- and Brdu/NSE-positive cells appeared except BrdU/TH-positive cells. BMSCs differentiated had better effect than that of BMSCs without differentiated and physiological saline group.

Rotator cuff tears are the most common conditions in sports medicine and attract increasing attention. Scar tissue healing at the tendon-bone interface results in a high rate of retears, making it a major challenge to enhance the healing of the rotator cuff tendon-bone interface. Biomaterials currently employed for tendon-bone healing in rotator cuff tears still exhibit limited efficacy.

Background: Ferroptosis is an iron-dependent regulatory cell death, which plays an essential role in bone loss. This study investigated whether the mechanism of risperidone (RIS)-induced bone loss is related to ferroptosis.
Methods: The schizophrenia mice were induced by administering MK-801.

Chemerin, an adipocyte-secreted adipokine, can regulate bone resorption and bone formation and is a promising therapy for postmenopausal osteoporosis. However, the effect of endogenous chemerin on intraosseous vascular remodeling in postmenopausal osteoporosis remains unclear. In this study, we investigated the effect of chemerin on osteogenesis formation and intraosseous vascular remodeling in ovariectomized Rarres2 knockout (Rarres2) mice.

Background: Osteoporosis (OP) is a prevalent global health concern, impacting millions of individuals, especially the elderly. The etiology of senile OP is associated with the imbalance of osteogenic and adipogenic differentiation in the bone marrow mesenchymal stem cells (BMSCs). The imbalance of BMSCs differentiation fate will leading to bone loss and lipids accumulation.

A biomechanical environment constructed exploiting the mechanical property of the extracellular matrix and external loading is essential for cell behaviour. Building suitable mechanical stimuli using feasible scaffold material and moderate mechanical loading is critical in bone tissue engineering for bone repair. However, the detailed mechanism of the mechanical regulation remains ambiguous.
