WNT pathway inhibitor; Inhibits Porcupine

Overview

Inhibitor of WNT Production-4 (IWP-4) inhibits WNT signaling by inactivating Porcupine, a membrane-bound O-acyltransferase responsible for palmitoylating WNT proteins, which is essential for WNT signaling ability and secretion (Chen et al.). IWP-4 impairs WNT pathway activity in vitro with an IC₅₀ value of 25 nM (Chen et al.).

A Simple Protocol for the Generation of Cardiomyocytes from Human Pluripotent Stem Cells. Sequiera GL et al. Methods in molecular biology (Clifton, N.J.) 2016 JAN

Abstract

Efficient generation of cardiomyocytes from pluripotent stem cells (PSCs) for multiple downstream applications such as regenerative medicine, disease modeling, and drug screening remains a challenge. Cardiomyogenesis may be regulated in vitro by a controlled differentiation process, which involves various signaling molecules and extracellular environment. Here, we describe a simple method to efficiently generate cardiomyocytes from human embryonic stem cells and human induced pluripotent stem cells.
Differentiation of human epidermal neural crest stem cells (hEPI-NCSC) into virtually homogenous populations of dopaminergic neurons. Narytnyk A et al. Stem cell reviews 2014 APR

Abstract

Here we provide a protocol for the directed differentiation of hEPI-NCSC into midbrain dopaminergic neurons, which degenerate in Parkinson's disease. hEPI-NCSC are neural crest-derived multipotent stem cells that persist into adulthood in the bulge of hair follicles. The experimental design is distinctly different from conventional protocols for embryonic stem cells and induced pluripotent stem (iPS) cells. It includes pre-differentiation of the multipotent hEPI-NCSC into neural stem cell-like cells, followed by ventralizing, patterning, continued exposure to the TGFβ receptor inhibitor, SB431542, and at later stages of differentiation the presence of the WNT inhibitor, IWP-4. All cells expressed A9 midbrain dopaminergic neuron progenitor markers with gene expression levels comparable to those in normal human substantia nigra. The current study shows for the first time that virtually homogeneous populations of dopaminergic neurons can be derived ex vivo from somatic stem cells without the need for purification, with useful timeliness and high efficacy. This novel development is an important first step towards the establishment of fully functional dopaminergic neurons from an ontologically relevant stem cell type, hEPI-NCSC.
Directed cardiomyocyte differentiation from human pluripotent stem cells by modulating Wnt/β-catenin signaling under fully defined conditions. Lian X et al. Nature protocols 2013 JAN

Abstract

The protocol described here efficiently directs human pluripotent stem cells (hPSCs) to functional cardiomyocytes in a completely defined, growth factor- and serum-free system by temporal modulation of regulators of canonical Wnt signaling. Appropriate temporal application of a glycogen synthase kinase 3 (GSK3) inhibitor combined with the expression of β-catenin shRNA or a chemical Wnt inhibitor is sufficient to produce a high yield (0.8-1.3 million cardiomyocytes per cm(2)) of virtually pure (80-98%) functional cardiomyocytes in 14 d from multiple hPSC lines without cell sorting or selection. Qualitative (immunostaining) and quantitative (flow cytometry) characterization of differentiated cells is described to assess the expression of cardiac transcription factors and myofilament proteins. Flow cytometry of BrdU incorporation or Ki67 expression in conjunction with cardiac sarcomere myosin protein expression can be used to determine the proliferative capacity of hPSC-derived cardiomyocytes. Functional human cardiomyocytes differentiated via these protocols may constitute a potential cell source for heart disease modeling, drug screening and cell-based therapeutic applications.
