The high frequency and mortality associated with breast cancer metastasis to bone has motivated efforts to elucidate tumor-stroma interactions in the bone microenvironment contributing to invasion and proliferation of metastatic cells. The development of engineered tissues has prompted the integration of engineered bone scaffolds into animal models as potential targets for metastatic spread. Si...

BACKGROUND Diabetic wounds are a major clinical challenge, because minor skin wounds can lead to chronic, unhealed ulcers and ultimately result in infection, gangrene, or even amputation. Studies on bone marrow derived mesenchymal stem cells (BMSCs) and a series of growth factors have revealed their many benefits for wound healing and regeneration. Platelet-rich plasma (PRP) may improve the env...

Bone marrow-derived mesenchymal stem cells (BMSCs) are able to differentiate into various types of skin cells and participate in skin regeneration and repair. Activin signaling can regulate wound healing and reepithelialization. The present study assessed the impact of activin B on BMSC-mediated cutaneous wound healing in rats and explored the possible mechanism involved. We found that CFSE-lab...

PURPOSE. To investigate the effects and possible mechanisms of rat bone marrow mesenchymal stem cell (BMSC) transplantation on the light-damaged retinal structure and the apoptosis of photoreceptors. METHODS. DAPI-labeled BMSCs were transplanted into the subretinal space of light-damaged Sprague-Dawley rats 10 days after exposure. BMSCs were cultivated with the supernatant of homogenized retina...

In this work, we investigated whether osteo-inductive constructs can be generated by isolationand expansion of sheep bone marrow stromal cells(BMSC) directly within three-dimensional (3D) ceramicscaffolds, bypassing the typical phase of monolayer (2D)expansion prior to scaffold loading. Nucleated cells fromsheep bonemarrowaspiratewere seeded into 3D ceramicscaffolds ...

Exosomes, extracellular nanovesicles secreted by various cell types, modulate the bone marrow (BM) microenvironment by regulating angiogenesis, cytokine release, immune response, inflammation, and metastasis. Interactions between bone marrow stromal cells (BMSCs) and multiple myeloma (MM) cells play crucial roles in MM development. We previously reported that BMSC-derived exosomes directly prom...

OBJECTIVE This study aims to investigate the potentially protective effect of neuroglobin (Ngb) gene-modified bone marrow mesenchymal stem cells (BMSCs) on traumatic spinal cord injury (SCI) in rabbits. METHODS A lentiviral vector containing an Ngb gene was constructed and used to deliver Ngb to BMSCs. Ngb gene-modified BMSCs were then injected at the SCI sites 24 hours after SCI. The motor f...

The aim of the current study was to confirm the effect and elucidate the mechanism of bone marrow mesenchymal stem cells (BMSCs) in acute myocardial infarction (AMI). AMI was induced in mini‑swine by ligating the left anterior descending coronary artery, and BMSCs (1x107) were injected via a sterile microinjection into the ischemic area. Six months postoperatively, electrocardiograph‑gated sing...

Despite the high cure rates in childhood acute lymphoblastic leukemia (ALL), relapsed ALL remains a significant clinical problem. Genetic heterogeneity does not adequately explain variations in response to therapy. The chemoprotective tumor microenvironment may additionally contribute to disease recurrence. This study identifies metabolic reprogramming of leukemic cells by bone marrow stromal c...

Intravascular transplantation of tissue factor (TF)-bearing cells elicits an instant blood-mediated inflammatory reaction (IBMIR) resulting in thrombotic complications and reduced engraftment. Here we studied the hemocompatibility of commonly used human white adipose tissue (WAT), umbilical cord (UC) and bone marrow stromal cells (BMSC) and devised a possible strategy for safe and efficient str...
