Introduction

Mouse- embryonic stem cell signaling regulation

The term "induced stem cell" refers to the new methods of gene introduction and expression that generate stem cells from both embryo and adult tissues.

A useful guide (online PDF document) to stem cells was produced in a report by the National Institute of Health (NIH, USA, May 2000) Stem Cells: A Primer (note large size - 4.84 Mb) and more recently NIH has established a Stem Cell information page.

RIKEN Panel Finds Misconduct in Reprogrammed Stem Cell Papers press release April 1, 2014 | Science April 2014 | Japanese research institute has opened an investigation into this groundbreaking stem cell study after concerns were raised about its credibility. The RIKEN investigation follows allegations on blog sites about the use of duplicated images in Obokata’s papers, and numerous failed attempts to replicate her results. Nature

  • The tumorigenicity of human embryonic and induced pluripotent stem cells PMID: 21390058 "Until recently, it was assumed that human induced pluripotent stem cells (HiPSCs) would behave like their embryonic counterparts in respect to their tumorigenicity. However, a rapidly accumulating body of evidence suggests that there are important genetic and epigenetic differences between these two cell types, which seem to influence their tumorigenicity."
  • iPS cells produce viable mice through tetraploid complementation[1] "Here we report the generation of several iPS cell lines that are capable of generating viable, live-born progeny by tetraploid complementation. These iPS cells maintain a pluripotent potential that is very close to ES cells generated from in vivo or nuclear transfer embryos. We demonstrate the practicality of using iPS cells as useful tools for the characterization of cellular reprogramming and developmental potency, and confirm that iPS cells can attain true pluripotency that is similar to that of ES cells."

Yamanaka Factors

Reprogramming MEF into ES-like cells 03.jpg

Yamanaka Factors[3][4] Are a set of 4 transcription factors when introduced into cells induces stem cell formation. These four transcription factors can be expressed from doxycycline (dox)-inducible lentiviral vectors.

OCT4

  • Octamer-binding transcription factor 3/4
  • Transcription factors containing the POU homeodomain


Links: OMIM - OCT4

SOX2

Early mouse Sox2 expression.[5]
  • Sry-related HMG-Box gene 2.
  • Sox2 is first expressed in very early (morula, blastocyst) development.
  • Forms a trimeric transcription complex with OCT4.
  • Gene targets - YES1, FGF4, UTF1 and ZFP206.

KLF4

  • Kruppel-like factor 4, zinc finger protein, transcription factor which acts as both an activator and repressor.
  • alternative names: Epithelial zinc finger protein EZF or Gut-enriched krueppel-like factor



Links: OMIM - KLF4

cMyc

  • The MYC protooncogene encodes a DNA-binding factor that can activate and repress transcription.
  • Ectopic expression of c-Myc can also cause tumorigenicity in offspring.
More recently shown that Oct4 together with either Klf4 or c-Myc is sufficient to generate iPS cells from neural stem cells.[6]
  • Tbx3 transcription factor significantly improves the quality of iPS cells.[7]

Generation of human melanocytes from induced pluripotent stem cells

PLoS One. 2011 Jan 13;6(1):e16182.

Ohta S, Imaizumi Y, Okada Y, Akamatsu W, Kuwahara R, Ohyama M, Amagai M, Matsuzaki Y, Yamanaka S, Okano H, Kawakami Y. Source Division of Cellular Signaling, Institute for Advanced Medical Research, Keio University School of Medicine, Tokyo, Japan. Abstract Epidermal melanocytes play an important role in protecting the skin from UV rays, and their functional impairment results in pigment disorders. Additionally, melanomas are considered to arise from mutations that accumulate in melanocyte stem cells. The mechanisms underlying melanocyte differentiation and the defining characteristics of melanocyte stem cells in humans are, however, largely unknown. In the present study, we set out to generate melanocytes from human iPS cells in vitro, leading to a preliminary investigation of the mechanisms of human melanocyte differentiation. We generated iPS cell lines from human dermal fibroblasts using the Yamanaka factors (SOX2, OCT3/4, and KLF4, with or without c-MYC). These iPS cell lines were subsequently used to form embryoid bodies (EBs) and then differentiated into melanocytes via culture supplementation with Wnt3a, SCF, and ET-3. Seven weeks after inducing differentiation, pigmented cells expressing melanocyte markers such as MITF, tyrosinase, SILV, and TYRP1, were detected. Melanosomes were identified in these pigmented cells by electron microscopy, and global gene expression profiling of the pigmented cells showed a high similarity to that of human primary foreskin-derived melanocytes, suggesting the successful generation of melanocytes from iPS cells. This in vitro differentiation system should prove useful for understanding human melanocyte biology and revealing the mechanism of various pigment cell disorders, including melanoma.
