The vast advances in technologies for the efficient generation of footprint-free induced pluripotent stem cells (iPSC) have led to the creation of several iPSC lines from varying sources, genetic backgrounds, and derivations in different medias and growth conditions, thus necessitating thorough characterization of the resulting cell lines.
One critical step in establishing iPSC lines involves the early identification of true iPSC clones and their subsequent characterization to ensure functional pluripotency. Various methods of characterization, ranging from visual morphological observation to the use of differentially expressed biomarkers are utilized for the initial identification of pluripotent cells. Dyes such as Alkaline Phosphatase Live Stain enable the early detection of emerging iPSC colonies that can be used in combination with morphological assessment to pick the right iPSC clone for further expansion. Established clones are further subjected to a combination of in vitro and in vivo cellular analysis to confirm functional pluripotency based on expression of self-renewal markers and trilineage differentiation potential. While such traditional methods have been successfully used, there is a need for a uniform standardized method for comprehensive characterization. Recently, the TaqMan® hPSC Scorecard™ Panel, a real-time PCR gene expression assay, provides a rapid molecular method to generate quantitative transcriptome data for the confirmation of functional pluripotency.
Join Uma Lakshmipathy, Principal Scientist at Thermo Fisher Scientific, to explore various options for identification and characterization of pluripotent stem cells.

An Integrated Workflow for the Isolation, Expansion, and Characterization of Hematopoietic Progenitors and their Conversion to Induced Pluripotent Stem Cells in Defined Culture Conditions
Wing Chang, PhD, Scientist & Steve Szilvassy, PhD, Director, Hematopoietic Products, Stemcell Technologies
Thursday, June 19th, 8-8:30am
Hematopoietic stem and progenitor cells are undoubtedly the most well studied tissue-specific precursor cells and now are commonly used for generating iPSCs. This presentation will describe the isolation, expansion, and characterization of human blood-derived CD34+ progenitors and erythroid cells, and methods for subsequent reprogramming of these cells to iPSCs using defined culture conditions. The tutorial will highlight STEMCELL Technologies integrated workflow for manipulating hematopoietic development in vitro and the generation of iPSCs from these precursors.

“Germany’s Bayer AG has trumped rival bidders for Merck & Co Inc’s consumer care business in a $14.2 billion deal, adding to a string of major cross-border deals in the healthcare industry. “This acquisition marks a major milestone on our path towards global leadership in the attractive non-prescription medicines business,” Bayer’s chief executive, Marijn Dekkers, said in a statement on Tuesday.”

“UCSF scientists may have found a clever way to use stem cells found in fat tissue to repair or replace bone damage from trauma, cancer or other injuries. The technique, tested in mice with broken shin bones, could improve current bone grafting procedures, which are common but sometimes not as successful as doctors and patients would like. Bone grafting is done to strengthen joint replacements, fuse vertebrae, improve healing of bad fractures or replace bone loss. It involves removing healthy bone from either the patient who needs the graft or from a donor, living or dead. But bone tissue isn’t always available and grafts don’t always work, so scientists have been hunting for techniques to improve or replace the procedure.”

“Leading global pharmaceutical companies have started to view their vast portfolios of older, established prescription drugs as vehicles for raising large sums of cash to fuel development of new medicines with far higher profit margins. France’s Sanofi (SASY.PA:) and U.S. drugmakers Merck & Co (MRK.N:) and Abbott Laboratories (ABT.N:) are exploring selling off their mature drugs that have lost patent protection, Reuters reported this week, citing people familiar with the plans. Officials at the three companies declined to comment.”

“Most of these projects have yet to enter clinical development, but the 20% annual increase in the number of biosimilars in clinical trials also indicates substantial advancement in the late-stage pipeline, says the study, from Decision Resources. South American companies have achieved the biggest increase in the number of biosimilars in development, driven by the large number of Productive Development Partnerships in Brazil between public organisations and industry, the study finds.”

“Organs-on-chips are piling up faster than body parts in Dr. Frankenstein’s lab. Such chips, microfluidic devices that amount to compact, three-dimensional cell culture versions of real organs, already exist for skin, cartilage, bone, gut, artery, heart, and kidney. And that’s not all: scientists anticipate linking together collections of organ chips to create body chips. But such a microfluidic “creature” would require, at a minimum, an artificial circulatory system, which would in turn require a constant supply of fresh blood cells. That’s where the scheme may falter. Unless an in vitro model of hematopoiesis can be developed that is capable of showing all the cellular diversity and complex functions of living marrow, no scientist will ever exult, “It’s alive!” while standing over a newly animated system of organ chips.”

“Two new studies out today show both the incredible promise of Stem Cell Research and its current limitations. In one, published in the journal Nature, researchers showed that they could repair damaged hearts by injecting these versatile stem cells into macaque monkeys. Heart disease is the leading cause of death, and if the same process can work in people, it could benefit hundreds of thousands a year. In the other study, published in Science Translational Medicine, five men were able to regrow leg muscles destroyed by accidents or military service. The researchers, from the University of Pittsburgh, inserted into the men’s muscles a “scaffold” of muscle tissue from a pig. Through aggressive physical therapy right after the surgery, the men’s own stem cells were encouraged to populate the scaffold and substantially rebuild their leg muscles.”

“Pfizer Inc. (PFE:US)’s plan to buy AstraZeneca Plc (AZN) probably will lead to billions of dollars in research cuts, the closure of laboratories and thousands of scientists being fired if history repeats itself. While drugmakers routinely refer to “synergies” in proposing large takeovers, the bottom line for patients is often fewer new medicines being pursued, according to a review of past large acquisitions by Pfizer. Since buying Wyeth in 2009, New York-based Pfizer has shed $4.6 billion in research spending, announced plans to close at least seven labs and narrowed its scientific focus to six areas of medicine, ending work in diseases such as asthma and allergies. Pfizer says the changes help make its search for drugs more focused and consumer savvy. Critics contest that the cuts have limited creative, early-stage research and slowed the process of bringing new drugs to market.
