We found a large induction of VEGF expression upon treatment of quiescent cells with serum, epidermal growth factor, transforming growth factor-beta 1, keratinocyte growth factor, or the proinflammatory cytokine tumor necrosis factor alpha, respectively.

The formation of islet-like cell clusters (ICCs) during a 6-day culture was stimulated two- to threefold by hepatocyte growth factor/scatter factor (HGF/SF) basic fibroblast growth factor (FGF)-2, and to a lesser extent by keratinocyte growth factor (FGF-7) and insulin-like growth factor-II (IGF-II).
|

|
The ICCs formed during HGF/SF stimulation consisted mainly of epithelial cells, whereas FGF-2-induced ICCs were predominantly nonepithelial.
|

|
Furthermore, although both FGF-2 and HGF/SF increased the total insulin content of the cultures, only HGF/SF increased the insulin content per DNA.
|
5 |
8013761
|
Quantitatively, HGF/SF stimulated a 2.3-fold increase in the proportion of insulin-positive cells and a 3-fold higher number of replicating beta-cells.
|

|
Blocking of the IGF-I receptor inhibited ICC formation but did not affect their insulin content.
|

|
Immunoneutralizing TGF-beta resulted in increased cell growth and insulin content, indicating the presence of an endogenous inhibitory TGF-beta activity in the model system.

A novel type I fibroblast growth factor receptor activates mitogenic signaling in the absence of detectable tyrosine phosphorylation of FRS2.
|

|
A novel variant of the fibroblast growth factor receptor type 1 (FGFR-1) was identified in human placental RNA.
|

|
Transfected L6 clones expressed respective proteins and bound (125)I-labeled FGF-2 with K(d) values of 99 pm (FGFR-1) and 26 pm (FGFR-1L).
|
11 |
10748122
|
FGF-1 and FGF-2 competed efficiently with (125)I-FGF-2 for binding to FGFR-1 and FGFR-1L, whereas FGF-4 was less efficient.
|
12 |
10748122
|
FGF-1, FGF-2, and FGF-4 enhanced mitogen-activated protein kinase (MAPK) activity, increased steady-state c-fos mRNA levels, and stimulated proliferation through either receptor, whereas KGF was without effect.
|
13 |
10748122
|
FGFR-1 expressing clones exhibited ligand-induced tyrosine phosphorylation of fibroblast growth factor receptor substrate 2 (FRS2), a 90-kDa adaptor protein that links FGFR-1 activation to the MAPK cascade.
|
14 |
10748122
|
These findings indicate that FGFR-1L binds FGF-1 and FGF-2 with high affinity and is capable of mitogenic signaling, but may activate MAPK to occur via non-classical signaling intermediates.

Here we show that the FGF receptors (FGFRs) 1 and 2, together with the ligands FGF1, FGF2, FGF4, FGF5, FGF7 and FGF10, are expressed in adult mouse beta-cells, indicating that FGF signalling may have a role in differentiated beta-cells.
|
16 |
11130726
|
We also show that Ipf1/Pdx1 is required for the expression of FGFR1 signalling components in beta-cells, indicating that Ipf1/Pdx1 acts upstream of FGFR1 signalling in beta-cells to maintain proper glucose sensing, insulin processing and glucose homeostasis.

In contrary, local application of keratinocyte growth factor (KGF) as well as insulin-like growth factor-I (IGF-I) have been shown to accelerate and improve anastomotic healing and mechanical stability in an animal model.

|
Taken together these data strongly suggest that FGF1 and FGF2 induce proliferation of pancreatic epithelial cells during the early post-natal period whereas FGF7 is not strictly specific for pancreatic cell proliferation.

KGF exerts strong mitogenic effect on the pancreatic duct cells, thus expanding the population of precursor cells that subsequently differentiate into insulin-producing beta-cells.

It could be shown that the applied anabolic combination significantly influenced the expression of the steroid receptor ERα, the keratinization factor CK8, the proinflammatory interleukins IL-1α and IL-1β, the growth factors FGF7, EGF, EGFR, IGF-1R, TGFα and LTF, the oncogen c-jun and other factors like actinβ and ubiquitin 3.

The entire differentiation process is carried out in serum-free chemically-defined media (CDM) and results in reliable and robust induction of pancreatic endoderm cells, marked by PDX1, and cell clusters co-expressing markers characteristic of beta cells, including PDX1 and insulin/C-peptide.
|
44 |
21855631
|
Varying the combinations of growth factors, we found that treatment of hESCs with bFGF, Activin A and BMP4 (FAB) together for 3-4days resulted in strong induction of primitive-streak and definitive endoderm-associated genes, including MIXL1, GSC, SOX17 and FOXA2.
|
45 |
21855631
|
Early proliferative foregut endoderm and pancreatic lineage cells marked by PDX1, FOXA2 and SOX9 expression are specified in EBs made from FAB-treated hESCs, but not from Activin A alone treated cells.
|
46 |
21855631
|
Further differentiation occurs after EBs are embedded in Matrigel and cultured in serum-free media containing insulin, transferrin, selenium, FGF7, nicotinamide, islet neogenesis associated peptide (INGAP) and exendin-4, a long acting GLP-1 agonist. 21-28days after embedding, PDX1 gene expression levels are comparable to those of human islets used for transplantation, and many PDX1(+) clusters are formed.
|
47 |
21855631
|
Almost all cells in PDX1(+) clusters co-express FOXA2, HNF1ß, HNF6 and SOX9 proteins, and many cells also express CPA1, NKX6.1 and PTF1a.
