Background: Hemophilia B is an X-linked hereditary disorder of blood coagulation system which is caused by factor IX (FIX) deficiency. Factor IX is a plasma glycoprotein that participates in the coagulation process leading to the generation of fibrin. Replacement of factor IX with plasma-derived or recombinant factor IX is the conventional treatment for hemophilia B to raise the factor IX le...
High-mobility group box 1 (HMGB1) mobilizes platelet-derived growth factor receptor alpha-positive (PDGFRα(+)) mesenchymal cells from bone marrow (BM) into circulation. However, whether HMGB1-induced endogenous PDGFRα(+) mesenchymal cells stimulate skin regeneration has been unclear. Here, we investigated the functions of the HMGB1/BM-PDGFRα(+) mesenchymal cell axis in the regeneration of mouse...
Serum-free media and the immunoregulatory properties of mesenchymal stem cells in vivo and in vitro.
BACKGROUND Mesenchymal stem cells are capable of self-renewal and multi-lineage differentiation. They are used extensively to treat several diseases. Traditionally, mesenchymal stem cells are cultured in serum-containing media, typically supplemented with fetal bovine serum (FBS). However, the variability of FBS is likely to skew experimental results. Although serum-free media used to expand me...
BACKGROUND Mesenchymal stem cells may offer therapeutic potential for asthma due to their immunomodulatory properties and host tolerability, yet prior evidence suggests that bloodborne progenitor cells may participate in airway remodeling. Here, we tested whether mesenchymal stem cells administered as anti-inflammatory therapy may favor airway remodeling and therefore be detrimental. METHODS ...
It is believed that a primitive cell type that maintains the mesenchymal compartment exists in the bone marrow. However, this putative mesenchymal stem/progenitor cell is yet to be identified and isolated. We are reporting the identification, isolation, and detailed characterization of the most primitive mesenchymal progenitor cells in the adult murine bone marrow, based on the expression of st...

Background and Aims: In the last decade, several studies have reported the isolation of stem cell population from different dental sources, while their mesenchymal nature is still controversial. The aim of this study was to isolate stem cells from mature human dental pulp and follicle and to determine their mesenchymal nature before differentiation based on the ISCT (International Society for C...
OBJECTIVE Although mesenchymal stem/stromal cells represent a promising therapeutic strategy for acute respiratory distress syndrome, clinical translation faces challenges, including scarcity of bone marrow donors, and reliance on bovine serum during mesenchymal stem/stromal cell proliferation. We wished to compare mesenchymal stem/stromal cells from human umbilical cord, grown in xeno-free con...
Background: Due to high differentiation potential and self-renewality, Mesenchymal Stem Cells are now widely considered by researchers in several diseases. FBS is used as a supplement in culture media for proliferation, differentiation, and other culture processes of MSCs, which is associated with transmission risk of a variety of infections as well as immune responses. PRGF derived from platel...
BACKGROUND Mesenchymal stromal cells are employed in various different clinical settings in order to modulate immune response. However, relatively little is known about the mechanisms responsible for their immunomodulatory effects, which could be influenced by both the cell source and culture conditions. DESIGN AND METHODS We tested the ability of a 5% platelet lysate-supplemented medium to s...
