Starter Guide to induced Pluripotent Stem Cells (iPSCs) Part 2:  Reprogramming and Transdifferentiation

The ultimate goal in the field of regenerative medicine is to replace lost or damaged cells. Here, I will discuss the two major processes by which an adult somatic cell is converted to a different cell type for regeneration and repair and situations where one process is favored over the other.

Starter guide to induced pluripotent stem cells (iPSCs) part 1:  A renaissance in regenerative medicine

Posted by Guest Blogger on Oct 30, 2018 9:04:26 AM

Stem cells are special types of cells that can develop or “differentiate” into more specialized cells with specific functions [1]. In many tissues, stem cells serve to replenish/replace damaged cells that no longer function adequately [1]. Stem cells’ ability to differentiate into multiple cell types makes them useful models for developmental processes and promising therapeutic tools. The two unique characteristics that define stem cells are:

Delivery Methods for Generating iPSCs

Posted by Beth Kenkel on Apr 17, 2018 9:37:57 AM

The field of induced pluripotent stem cells (iPSCs) has been around for 10 years. In that time, scientists have used almost all available approaches for generating iPSCs. The generation of iPSCs is relatively simple in concept: ectopically express a cocktail of stem cell reprogramming factors and wait for cells to de-differentiate. However it’s difficult, especially as a newbie reprogrammer, to decide which method to use. This post provides a brief overview of reprogramming methods with the goal of helping readers choose a strategy suited to their research.

pCXLE toolkit: Efficient episomal plasmid-based method to reprogram peripheral blood cells to iPSCs

Posted by Guest Blogger on Dec 14, 2017 9:08:09 AM

This post was contributed by Kusumika (Kushi) Mukherjee, a Postdoc at Massachussetts General Hospital.

A little over a decade back when Yamanaka and colleagues reported that it is possible to reprogram differentiated cells into induced pluripotent stem cells (iPSCs) by the addition of reprogramming (or “Yamanaka”) factors, they changed the landscape of regenerative medicine. Their work opened up vast possibilities for the clinical and therapeutic applications of iPSCs. The generation of human iPSCs (hiPSCs) now provides an opportunity to develop and use patient-specific somatic cells that are otherwise difficult to obtain. These can then be used to perform cell therapy and to model diseases in vitro.

Stem Cell Models for Disease & Open Science: Interview with Darrell Kotton

Posted by Tyler Ford on Jul 7, 2017 9:32:42 AM

Darrell Kotton is the director of the Center for Regenerative Medicine at Boston University Medical School. Darrell’s research focuses on the lungs, and, among other projects, using stem cells to develop in vitro models for lung disease. Darrell strives to promote open source biology in his own lab, at the Center for Regenerative Medicine, and within the biomedical research community. Along these lines, Darrell recently joined the Addgene Board of Directors where he hopes to help keep us focused on our core mission to promote scientific sharing. Listen to learn more about Darrell, his research, and his focus on open science.
