To identify low abundance autocrine growth factors in CHO cell conditioned media, we utilized a label-free shotgun proteomics approach. CHO cell conditioned media were harvested from fed batch bioreactors and concentrated using methanol/chlorofrom precipitation. Proteins in the samples were then su...
Nitric oxide (NO) produced by macrophages (MØs) is toxic to both host tissues and invading pathogens and its regulation is therefore essential to suppress host cytotoxicity. MØ arginase 1 (Arg1) inhibits NO production by competing with NO synthases for arginine, the common substrate of NO synthases ...
The neural stem cell decision to self-renew or differentiate is tightly regulated by its microenvironment. Here, we have asked about this microenvironment, focusing on growth factors in the embryonic cortex at a time when it is largely comprised of neural precursor cells (NPCs) and newborn neurons. ...
Myostatin (gene symbol: Mstn) is an autocrine and paracrine inhibitor of muscle growth. Pregnant mice with genetically reduced levels of myostatin give birth to offspring with greater adult muscle mass and bone biomechanical strength. However, maternal myostatin is not detectable in fetal cir...
The role of paracrine/autocrine factors in inflammation, immune response and tumor development is well established. There is also an evidence that some of the cytokines there involved may participate in the regulation of the male gonads. However, their involvement in pathogenesis of male infertilit...

Human growth plate chondrocytes were isolated from the distal femoral growth plate from 3 different adolescents undergoing epiphysiodesis. Cell were isolated and grown in monolayers, long term, in 20% serum. Cells were replated and cultured 48 h in 0.5% serum.
