Since the discovery of adipose-derived mesenchymal stem cell (ADSC) in more than ten years, a great progress has been made from its basic research to clinical application. Compared with bone marrow mesenchymal stem cells, ADSCs are more abundant in reserve, easier to obtain with fewer injuries and less complications. These cells have multiple differentiation potential and can differentiate into adipocytes, chondrocytes and osteoblasts with the influence of different inducing factors. Early studies of ADSCs mainly focused on the ability of multi-directional differentiation, espe-cially on the regeneration of bone defects and cartilage tissue...

It is well appreciated that high density lipoprotein (HDL) and bone physiology and pathology are tightly linked. Studies, primarily in mouse models have shown that dysfunctional and/or disturbed HDL can affect bone mass through many different ways. Specifically, reduced HDL levels have been associated with the development of an inflammatory microenvironment that affects the differentiation and function of osteoblasts. In addition, perturbation in HDL metabolic pathways favor adipoblastic and restrain osteoblastic differentiation through, among others, the modification of specific bone-related chemokines and signaling cascades...

BACKGROUND: While current therapies for osteoporosis focus on reducing bone resorption, the development of therapies to regenerate bone may also be beneficial. Promising anabolic therapy candidates include phytoestrogens, such as daidzein, which effectively induce osteogenesis of adipose-derived stromal cells (ASCs) and bone marrow stromal cells (BMSCs). PURPOSE: To investigate the effects of glyceollins, structural derivatives of daidzein, on osteogenesis of ASCs and BMSCs...

Based on several pre-clinical studies, cell-based therapy has emerged as a potential new therapeutic for ARDS. Of the various cell-based therapy options, mesenchymal stromal cells (MSCs) from bone marrow, adipose tissue and umbilical cord have the most experimental data to support their potential efficacy for lung injury from both infectious and non-infectious causes. Mechanistically, MSCs exert their beneficial effects by release of paracrine factors, microvesicles, and transfer of mitochondria, all of which have anti-inflammatory and pro-resolving effects on injured lung endothelium and alveolar epithelium, including enhancing the resolution of pulmonary edema by upregulating sodium-dependent alveolar fluid clearance...

Docosahexaenoic acid (DHA) is an omega-3 fatty acid obtained from the diet or synthesized from alpha-linolenic acid through the action of fatty acid elongases (ELOVL) and desaturases. DHA plays important roles in the central nervous system as well as in peripheral organs and is the precursor of several molecules that regulate resolution of inflammation. In the present study, we questioned whether impaired synthesis of DHA affected macrophage plasticity and polarization both in vitro and in vivo models. For this we investigated the activation status and inflammatory response of bone marrow-derived M1 and M2 macrophages obtained from mice deficient of Elovl2 (Elovl2(-/-)), a key enzyme for DHA synthesis in mammals...

During culture expansion, multipotent mesenchymal stromal cells (MSC) differentially express aldehyde dehydrogenase (ALDH), an intracellular detoxification enzyme that protects long-lived cells against oxidative stress. Thus, MSC selection based on ALDH-activity may be used to reduce heterogeneity and distinguish MSC subsets with improved regenerative potency. After expansion of human bone marrow-derived MSC, cell progeny were purified based on low versus high ALDH-activity by fluorescence activated cell sorting, and each subset was compared for multipotent stromal and pro-vascular regenerative functions...

OBJECTIVES: The current treatment options for neuropathic pain due to nerve injuries are limited and largely unsatisfactory. Mesenchymal stem cell transplantation (MSC) has shown promise as an emerging therapy for neuropathic pain. However, a number of critical parameters, including the sources of cells, the number of cells, and routes of transplantation, need to be elucidated before it can be tested clinically. METHODS: MSCs were isolated from rat bone marrow (rBM-MSCs) and adipose tissue (rAD-MSCs) and characterized by flow cytometry and functional differentiation...

NLRP3 (Nod-like receptor family pyrin domain containing 3) inflammasome has been reported to contribute to obesity-induced inflammation and insulin resistance. However, there are few drugs targeting NLRP3 inflammasome for the treatment of insulin resistance. In the present study, we showed that berberine (BBR) significantly suppressed saturated fatty acid palmitate (PA)-induced NLRP3 inflammasome activation and interleukin-1β (IL-1β) release in macrophages, which was one of the most important mediators in the insulin sensitivity of adipose tissue...

BACKGROUND: Mesenchymal stem/stromal cells (MSCs) represent an attractive tool for cell-based cancer therapy mainly because of their ability to migrate to tumors and to release bioactive molecules. However, the impact of MSCs on tumor growth has not been fully established. We previously demonstrated that murine MSCs show a strong tropism towards glioblastoma (GBM) brain xenografts and that these cells are able to uptake and release the chemotherapeutic drug paclitaxel (PTX), maintaining their tropism towards the tumor...

Bone is a plastic tissue with a large healing capability. However, extensive bone loss due to disease or trauma requires extreme therapy such as bone grafting or tissue-engineering applications. Presently, bone grafting is the gold standard for bone repair, but presents serious limitations including donor site morbidity, rejection, and limited tissue regeneration. The use of stem cells appears to be a means to overcome such limitations. Bone marrow mesenchymal stem cells (BMSC) have been the choice thus far for stem cell therapy for bone regeneration...

For the treatment of diseases affecting bones using bone regenerative medicine, there is an urgent need to develop safe, inexpensive drugs that can strongly induce bone formation. In the present study, we systematically investigated the effects of icaritin, a metabolic product of icariin, on the osteogenic differentiation of human bone marrow‑derived mesenchymal stem cells (hBMSCs) and human adipose tissue‑derived stem cells (hADSCs) in vitro. After treatment with icaritin at concentrations of 10‑8-10‑5 M, hBMSCs and hADSCs were examined for alkaline phosphatase activity, osteocalcin (OC) secretion, matrix mineralization and expression levels of bone‑related mRNA and proteins...

The bone marrow (BM) contains controlled specialized microenvironments, or niches, that regulate the quiescence, proliferation, and differentiation of hematopoietic stem and progenitor cells (HSPC). The glucose-dependent insulinotropic polypeptide (GIP) is a gut-derived incretin hormone that mediates postprandial insulin secretion and has anabolic effects on adipose tissue. Previous studies demonstrated altered bone microarchitecture in mice deficient for GIP receptor (Gipr(-/-) ), as well as the expression of high-affinity GIP receptor by distinct cells constructing the BM HSPC niche...

A hallmark of aged mesenchymal stem/progenitor cells (MSCs) in bone marrow is the pivot of differentiation potency from osteoblast to adipocyte coupled with a decrease in self-renewal capacity. However, how these cellular events are orchestrated in the aging progress is not fully understood. In this study, we have used molecular and genetic approaches to investigate the role of forkhead box P1 (FOXP1) in transcriptional control of MSC senescence. In bone marrow MSCs, FOXP1 expression levels declined with age in an inverse manner with those of the senescence marker p16INK4A...
