Also, VEGF-A has already been connected to glial differentiation of neural progenitor cells (Kim et al., 2009; Mani et al., 2005).
Since production of specialized metabolites is tightly connected to morphological differentiation and depends on a plethora of environmental conditions, expression of CSRs hinges on a variety of other pleiotropic, higher-level regulators that sense and transmit signals to them.
Expression of microphthalmia-associated transcription factor (MITF), the signal transducer and activator of transcription 3 (STand), and their co-regulation via protein inhibitor of activated STAT3 (PIare), all all tightly connected to cell differentiation, proliferation and survival.
In A. nidulans, cross-pathway control is connected to cellular differentiation as increase in activity of the CpcA resulted in a reversible block of fruit body formation (Hoffmann et al. 2000).
Serum-induced p68 expression in Swiss 3 T3 fibroblasts is involved in cellular proliferation and also connected to organ differentiation and maturation of the foetus [ 37]. p68 regulates the expression of several oncogenes through co-activation of β-catenin-mediated transcription, and controls tumour growth and metastasis.
EMT pathways are also tightly connected to determination and differentiation programs, and are reactivated in adult tissues following injury or exposure to toxic agents.
Here we analyzed the impact of the microRNAs miR-17, -20a, and -106b on cell cycle arrest connected to neuronal lineage differentiation of USSC induced by retinoic acid containing neuronal induction medium XXL.
EMT pathways are also tightly connected to determination and differentiation programmes, and are reactivated in adult tissues following injury or exposure to toxic agents.
There is no direct proof for this hypothesis yet, but interactions between different cell types play important roles in other processes connected to hepatocyte-specific differentiation and gene expression.
