Stem cell-derived hepatocytes may be an alternative cell source to treat liver diseases or to be used for pharmacological purposes. We developed a protocol that mimics mammalian liver development, to differentiate cells with pluripotent characteristics to hepatocyte-like cells. The protocol supports the stepwise differentiation of human embryonic stem cells (ESC) to cells with characteristics of primitive streak (PS)/mesendoderm (ME)/definitive endoderm (DE), hepatoblasts, and finally cells with phenotypic and functional characteristics of hepatocytes. Remarkably, the same protocol can also differentiate rat multipotent adult progenitor cells (rMAPCs) to hepatocyte-like cells, even though rMAPC are isolated clonally from cultured rat bone marrow (BM) and have characteristics of primitive endoderm cells. A fraction of rMAPCs can be fated to cells expressing genes consistent with a PS/ME/DE phenotype, preceding the acquisition of phenotypic and functional characteristics of hepatocytes. Although the hepatocyte-like progeny derived from both cell types is mixed, between 10–20% of cells are developmentally consistent with late fetal hepatocytes that have attained synthetic, storage and detoxifying functions near those of adult hepatocytes. This differentiation protocol will be useful for generating hepatocyte-like cells from rodent and human stem cells, and to gain insight into the early stages of liver development.

For diagnosing and annihilating cancer in the human body, herein, we have adopted a one pot convenient synthetic protocol to synthesize a library of half sandwich Ru(II)-p-cymene-N^N complexes under continuous sonication and isolated their regioisomers by preparative thin layer chromatography followed by justification of stability using DFT. The present work has resulted in a library of ruthenium arene complexes and their isolated regioisomers following environmentally benign green processes and their screening of anticancer activity in terms of cytotoxicity and selectivity against cancer cell lines where [(η⁶-p-cymene)RuCl{2-(5,6-dichloro-1H-benzo[d]imidazole-2-yl)quinolone}] (11j) has been elicited to be significantly more potent as well as selective in Caco-2 and HeLa cell lines than the normal HEK-293 cell line compared to cisplatin and it has even shown marked cytotoxicity against the more aggressive HT-29 colorectal cancer cell line being capable of producing oxidative stress or arresting the cell cycle. Moreover, these types of Ru(II)–arene complexes exhibited excellent binding efficacy with DNA and the compounds [(η⁶-p-cymene)RuCl{5-chloro-2-(6-(4-chlorophenyl)pyridin-2-yl)benzo[d]thiazole}]PF₆ (8l4), [(η⁶-p-cymene)Ru-2-(6-(benzofuran-2-yl)pyridin-2-yl)-5-chlorobenzo[d]thiazole (8l9) and [(η⁶-p-cymene)RuCl{2-(6-nitro-1H-benzo[d]imidazol-2-yl)quinolone}]Cl (11f′) and might be applied for cancer theranostic treatment due to their good fluorescence properties and remarkable potency.
