Abstract
Porphyra 334 (P334), a mycosporine-like amino acid (MAA), is a secondary metabolite found in diverse marine and terrestrial organisms and has several beneficial effects on fibroblast proliferation, wound healing, and antioxidant activity. Here, we report that P334 accelerates the cell reprogramming process of mouse tail-tip fibroblasts (TTFs) and human dermal papilla (HDP) cells into induced pluripotent stem cells (iPSCs). We found that P334 significantly improved the cell reprogramming efficiency by activating the tri-methylation of histone 3 lysine 4 (H3K4me3), which controls mesenchymal to epithelial transition (MET) during the reprogramming process. Thus, we found that P334 directly regulates epigenetic changes, providing an efficient approach for natural compound-based cell reprogramming.

Morgani S, Nichols J, Hadjantonakis AK. The many faces of Pluripotency: in vitro adaptations of a continuum of in vivo states. BMC DEVELOPMENTAL BIOLOGY 2017; 17:7. [PMID: 28610558 PMCID: PMC5470286 DOI: 10.1186/s12861-017-0150-4] [Citation(s) in RCA: 105] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/28/2017] [Accepted: 06/01/2017] [Indexed: 12/20/2022]
Abstract
Pluripotency defines the propensity of a cell to differentiate into, and generate, all somatic, as well as germ cells. The epiblast of the early mammalian embryo is the founder population of all germ layer derivatives and thus represents the bona fide in vivo pluripotent cell population. The so-called pluripotent state spans several days of development and is lost during gastrulation as epiblast cells make fate decisions towards a mesoderm, endoderm or ectoderm identity. It is now widely recognized that the features of the pluripotent population evolve as development proceeds from the pre- to post-implantation period, marked by distinct transcriptional and epigenetic signatures. During this period of time epiblast cells mature through a continuum of pluripotent states with unique properties. Aspects of this pluripotent continuum can be captured in vitro in the form of stable pluripotent stem cell types. In this review we discuss the continuum of pluripotency existing within the mammalian embryo, using the mouse as a model, and the cognate stem cell types that can be derived and propagated in vitro. Furthermore, we speculate on embryonic stage-specific characteristics that could be utilized to identify novel, developmentally relevant, pluripotent states.
