12, 21 Another concern about consolidation use is whether a bone marrow in the process of recovering and regenerating from the effects of recent myelotoxic chemotherapy can sustain safely the effect of RIT.
Our results support a role for elevated sarcoplasmic CaMKII content for accelerating muscle contraction and relaxation in regenerating muscle via effects that include the enhanced expression of fast myosin heavy chain and sarcoplasmic reticulum associated SERCA2 and ANXV protein, but not in mitochondrial biogenesis.
Injection of FGF-2 into the muscle of mdx mice increases the number of regenerating myofibers and this effect is positively correlated to the quantity of FGF-2 injected [ 34].
It is worth noting that while inflammatory cytokines are essential for recruitment of satellite cells to muscle fibers [41], pro-myogenic factors, such as IGF-I [52], promote regeneration by accelerating the modulation of inflammatory cytokine effects in regenerating muscles.
This enabled us to compare the effects on regenerating bone with those on bone undergoing normal baseline remodeling.
Our model does not resolve if other signaling pathways required for fin ray regeneration, including fibroblast growth factor (FGF) and Hedgehog (reviewed in Gemberling et al., 2013), interface with Wnt/β-catenin and BMPs in osteoblasts or have secondary effects on regenerating bone.
My colleagues from the University of Pennsylvania and I extended this research in this mammalian model, which more closely tracks the effect regenerated cardiac tissue could have in humans.
Therefore the anti-inflammatory effect of ACh on regenerating skeletal muscle may be dominant compared with direct effects of Ach on endothelial cells.
Next, we wanted to determine whether the beneficial effect of pregnancy on muscle regeneration, demonstrated by regenerating myotubes, is due to an increase in satellite cell number.
Hsp70 overexpression had a slightly hypertrophic effect on the regenerating fiber size, which was not further increased by AVP treatment, either alone or in combination with TNF (Fig. 8C).
