M-CSF Priming of Osteoclast Precursors Can Cause Osteoclastogenesis-Insensitivity, Which Can be Prevented and Overcome on Bone

Osteoclasts and macrophages share progenitors that must receive decisive lineage signals driving them into their respective differentiation routes. Macrophage colony stimulation factor M-CSF is a common factor; bone is likely the stimulus for osteoclast differentiation. To elucidate the effect of both, shared mouse bone marrow precursor myeloid blast was pre-cultured with M-CSF on plastic and on bone. M-CSF priming prior to stimulation with M-CSF and osteoclast differentiation factor RANKL resulted in a complete loss of osteoclastogenic potential without bone. Such M-CSF primed cells expressed the receptor RANK, but lacked the crucial osteoclastogenic transcription factor NFATc1. This coincided with a steeply decreased expression of osteoclast genes TRACP and DC-STAMP, but an increased expression of the macrophage markers F4/80 and CD11b. Compellingly, M-CSF priming on bone accelerated the osteoclastogenic potential: M-CSF primed cells that had received only one day M-CSF and RANKL and were grown on bone already expressed an array of genes that are associated with osteoclast differentiation and these cells differentiated into osteoclasts within 2 days. Osteoclastogenesis-insensitive precursors grown in the absence of bone regained their osteoclastogenic potential when transferred to bone. This implies that adhesion to bone dictates the fate of osteoclast precursors. Common macrophage-osteoclast precursors may become insensitive to differentiate into osteoclasts and regain osteoclastogenesis when bound to bone or when in the vicinity of bone. J. Cell.

Uso de células-tronco para o tratamento de tendinite em eqüinos

Brazil has the fourth largest horse herd in the world, this is due the recognition and appreciation that the different equestrian games are having within the country. Injuries of the tendon, especially in the digital flexor tendon, are the main cause of athletic life reduction among horses. The treatment of tendinitis in horses seeks full recovery of the damage tissue reestablishing the function previously lost, however conventional treatments have proven to be ineffective when considered the quality of the scar tissue and the rate of recurrence. Due to this, the use of adult stem cells to the treatment of musculoskeletal injuries of horses has been studied for some time. This method of treatment consists of aspiration of bone marrow or removal of subcutaneous fat tissue and implantation of these cells in the injured tissue. After obtaining the bone marrow the implantation can be performed with total bone marrow, with the mononuclear fraction of MSC or with cells cultured in vitro. From the fat tissue is used the stromal vascular fraction obtained by collagenase digestion, followed or not by cell culture. According to some studies, cell therapy with material obtained from bone marrow or adipose tissue has shown to be viable, given that these materials are abundant in repair components such as mesenchymal stem cells (MSC), growth factors and other components of the collagen matrix. Several studies using both types of cells have shown great potential and promising clinical results. However, knowledge of the biology and characterization of these cells remain largely unknown, and therefore is needed great care and caution when using stem cells for the treatment of musculoskeletal disorders in horses
