Abstract
Fibroblast growth factor 4 (FGF4) is a crucial growth factor for the development of mammalian embryos. We previously produced hexahistidine-tagged, bovine and porcine FGF4 (Pro(32) to Leu(206) ) proteins without a secretory signal peptide at the aminoterminus in Escherichia coli. Here, we found that these were unstable; site-specific cleavage between Ser(54) and Leu(55) in both FGF4 derivatives was identified. In order to generate stable FGF4 derivatives and to investigate their biological activities, aminoterminally truncated and hexahistidine-tagged bovine and porcine FGF4 (Leu(55) to Leu(206) ) proteins, termed HisbFGF4L and HispFGF4L, respectively, were produced in E. coli. These FGF4 derivatives were sufficiently stable and exerted mitogenic activities in fibroblasts. Treatment with the FGF4 derivatives promoted the phosphorylation of ERK1/2, which are crucial kinases in the FGF signaling pathway. In the presence of PD173074, an FGF receptor inhibitor, the phosphorylation of ERK1/2 was inhibited and resulted in abolition of the growth-promoting activity of FGF4 derivatives. Taken together, we demonstrate that HisbFGF4L and HispFGF4L are capable of promoting the proliferation of bovine- and porcine-derived cells, respectively, via an authentic FGF signaling pathway. These FGF4 derivatives may be applicable for dissecting the roles of FGF4 during embryogenesis in cattle and pigs.

Abstract
In mice, fibroblast growth factor 4 (Fgf4) is a crucial gene for the generation of trophectoderm, progenitor cells of the placenta. Therefore, exogenous FGF4 promotes the isolation and maintenance of trophoblast stem cells from preimplantation embryos. We previously produced a 6× histidine (His)-tagged, mouse FGF4 (Pro(31)-Leu(202)) without a secretory signal peptide at the amino-terminus, referred to as HismFGF4, in Escherichia coli. Here, we found that HismFGF4 was unstable, such as in phosphate-buffered saline. In these conditions, site-specific cleavage between Ser(50) and Leu(51) was identified. In order to generate stable mouse FGF4 derivatives, a 6× His-tagged mouse FGF4 (Leu(51)-Leu(202)), termed HismFGF4L, was expressed in E. coli. HismFGF4L could be purified from the supernatant of cell lysates by heparin column chromatography. In phosphate-buffered saline, HismFGF4L was relatively stable. HismFGF4L exerted significant mitogenic activities at concentrations as low as 0.01 nM (P < 0.01) in mouse embryonic fibroblast Balb/c 3T3 cells expressing FGF receptor 2. In the presence of PD173074, an FGF receptor inhibitor, the growth-promoting activity of HismFGF4L was abolished. Taken together, we suggest that aminoterminally truncated HismFGF4L is capable of promoting the proliferation of mouse-derived cells via an authentic FGF signaling pathway. We consider that HismFGF4L is useful as a derivative of mouse FGF4 protein for analyzing the effects of mouse FGF4 and for stimulating cell growth of mouse-derived cells, such as trophoblast stem cells. Our study provides a simple method for the production of a bioactive, stable mouse FGF4 derivative in E. coli.

Abstract
Fibroblast growth factor 4 (FGF4) is considered as a crucial gene for tumorigenesis in humans and the development of mammalian embryos. The secreted, mature form of human FGF4 is thought to be comprised of 175 amino acid residues (proline(32) to leucine(206), Pro(32)-Leu(206)). Here, we found that bacterially expressed, 6× histidine (His)-tagged human FGF4 (Pro(32)-Leu(206)) protein, referred to as HishFGF4, was unstable such as in phosphate-buffered saline. In these conditions, site-specific cleavage, including between Ser(54) and Leu(55), in HishFGF4 was identified. In order to generate stable human FGF4 derivatives, a 6× His-tagged human FGF4 (Leu(55)-Leu(206)), termed HishFGF4L, was expressed in Escherichia coli. HishFGF4L could be purified from the supernatant of cell lysates by heparin column chromatography. In phosphate-buffered saline, HishFGF4L was considered as sufficiently stable. HishFGF4L exerted significant mitogenic activities in mouse embryonic fibroblast Balb/c 3T3 cells. In the presence of PD173074, an FGF receptor inhibitor, the growth-stimulating activity of HishFGF4L disappeared. Taken together, we suggest that HishFGF4L is capable of promoting cell growth via an authentic FGF signaling pathway. Our study provides a simple method for the production of a bioactive human FGF4 derivative in E. coli.

Abstract
The homeoprotein EGAM1C was identified in preimplantation mouse embryos and embryonic stem (ES) cells. To explore the impact of EGAM1C on the hallmarks of mouse ES cells, MG1.19 cells stably expressing EGAM1C at levels similar to those in blastocysts were established using an episomal expression system. In the presence of leukemia inhibitory factor (+LIF), control transfectants with an empty vector formed flattened cell colonies, whileEgam1ctransfectants formed compacted colonies with increased E-CADHERIN expression. InEgam1ctransfectants, the cellular contents of POU5F1 (OCT4), SOX2, TBX3, and NANOG increased. Cell growth was accelerated in an undifferentiated state sustained by LIF and in the course of differentiation. During clonal proliferation, EGAM1C stabilized the undifferentiated state. In adherent culture conditions, EGAM1C partly inhibited the progression of differentiation at least within a 4-day culture period in the presence of retinoic acid by preventing the downregulation of LIF signaling with a robust increase in TBX3 expression. Conversely, EGAM1C enhanced the expression of lineage marker genesFgf5(epiblast),T(mesoderm),Gata6(primitive endoderm), andCdx2(trophectoderm) in −LIF conditions. In embryoid bodies expressing EGAM1C, the expression of marker genes for extraembryonic cell lineages, includingTpbpa(spongiotrophoblast) andPlat(parietal endoderm), increased. These results demonstrated that the ectopic expression of EGAM1C is capable of affecting the stabilization of an undifferentiated state and the progression of differentiation in MG1.19 ES cells, in addition to affecting cellular morphology and growth.
