Hematopoiesis is a balance among quiescence, self-renewal, proliferation, and differentiation, which is believed to be firmly adjusted through interactions between hematopoietic stem and progenitor cells (HSPCs) with the microenvironment. This microenvironment is derived from a common progenitor of mesenchymal origin and its signals should be capable of regulating the cellular memory of transcriptional situation and lead to an exchange of stem cell genes expression. Mesenchymal stem cells (MSCs) have self-renewal and differentiation capacity into tissues of mesodermal origin, and these cells can support hematopoiesis through release various molecules that play a crucial role in migration, homing, self-renewal, proliferation, and differentiation of HSPCs. Studies on the effects of MSCs on HSPC differentiation can develop modern solutions in the treatment of patients with hematologic disorders for more effective Bone Marrow (BM) transplantation in the near future. However, considerable challenges remain on realization of how paracrine mechanisms of MSCs act on the target tissues, and how to design a therapeutic regimen with various paracrine factors in order to achieve optimal results for tissue conservation and regeneration. The aim of this review is to characterize and consider the related aspects of the ability of MSCs secretome in protection of hematopoiesis.

Humerus greater tuberosity (HGT) avulsion fracture is one of the most common types of proximal humerus fractures. The presence of motion and gap lead to the failure of implants, due to the force pulling from the supraspinatus. In this work, electrospinning technology was applied to fabricate PCL-PEG/CS/AST nanofiber with superior biocompatibility and mechanical property.

Endometrial injury caused by repeated uterine procedures, infections, inflammation, or uterine artery dysfunction can deplete endometrial stem/progenitor cells and impair regeneration, thereby diminishing endometrial receptivity and evidently lowering the live birth, clinical pregnancy, and embryo implantation rates. Currently, safe and effective clinical treatment methods or gene-targeted therapies are unavailable, especially for severe endometrial injury. Umbilical cord mesenchymal stem cells and their extracellular vesicles are characterized by their simple collection, rapid proliferation, low immunogenicity, and tumorigenicity, along with their involvement in regulating angiogenesis, immune response, cell apoptosis and proliferation, inflammatory response, and fibrosis, Therefore, these cells and vesicles hold broad potential for application in endometrial repair.

Peripheral nerve injury (PNI) is a common disease that is difficult to nerve regeneration with current therapies. Fortunately, Zou demonstrated the role and mechanism of bone marrow derived mesenchymal stem cells (BMSCs) in promoting nerve regeneration, revealing broad prospects for BMSCs transplantation in alleviating PNI. We confirmed the fact that BMSCs significantly alleviate PNI, but there are shortcomings such as low cell survival rate and immune rejection, which limit the wide application of BMSCs.

Despite the established anti-fibrotic effects of mesenchymal stem cells (MSCs), numerous challenges hinder their clinical application. A recent study demonstrated that microvesicles (MVs) from MSCs (MSC-MVs) could attenuate ARDS-related pulmonary fibrosis and enhance lung function hepatocyte growth factor mRNA transcription.

Background: Human mesenchymal stromal cells (MSCs) possess regenerative potential due to pluripotency and paracrine functions. However, their stemness and immunomodulatory capabilities are sub-optimal in conventional two-dimensional (2D) culture.
Aim: To enhance the efficiency and therapeutic efficacy of MSCs, an -like 3D culture condition was applied.
