The pioneering induced pluripotent stem cell (IPSC) clinical study in Japan led by top stem cell clinical researcher Dr. Masayo Takahashi has been stopped reports the WSJ in Japan. This development is confirmed by other sources and in a PDF report by RIKEN (in Japanese here). One patient was transplanted in September 2014 with their own IPSC-derived […]

Organoids are pretty big in stem cells right now with the last couple of years having attracted a lot of media attention on mini lungs, mini brains, mini kidneys, mini guts and more, giving the impression that scientists know how to specify and organise cells into mini functional organs in the lab. Organoids have become

The day of plenary is the most enjoyable in my view including at ISSCR 2015 on the first day with a Yamanaka talk. You don’t need to make the choice between sessions and the judgement on the viability of shifting sessions versus staying put and listening to the slightly less relevant. ISSCR 2015 plenary was,

The stem cell biotech Advanced Cell Technology (ACT) reported new, positive data in a paper in Lancet from their clinical trials using retinal pigmented epithelial cells (RPEs) made from human embryonic stem cells (hESC) for treatment of different forms of macular degeneration (MD). The paper was entitled “Human embryonic stem cell-derived retinal pigment epithelium in patients with age-related

Stem cell biotech BioTime announced the news today that its subsidiary Cell Cure Neurosciences (Cell Cure) has filed an IND with the FDA for an embryonic stem (ES) cell-based therapy for Dry age-related macular degeneration (AMD). The product to be tested is OpRegen, which the company indicates is “the first IND for an ES cell-based

Before the two STAP cell papers were published in Nature in January of 2014, much of the same data was reportedly submitted as single papers to other high-profile journals including Science. In these cases, the proto-STAP papers as we might call them were rejected. But why? Until now we largely could only speculate. However, the reviews

Nikkei is reporting that the RIKEN internal attempt to replicate so-called STAP (acid bath) cells has failed. Update: apparently, although RIKEN calls the efforts preliminary, the team tried to make STAP an amazing 22 times and 22 times it failed. The rumors for weeks in the stem cell gapevine that RIKEN itself could not get

Who is trying, via the name BioGatekeeper, Inc., to nullify Yamanaka’s patent on cellular reprogramming to produce induced pluripotent stem (iPS) cells? The readers of this blog never cease to amaze me. What an informed, energetic, bright group. Within just days they may have collectively shed some light on an intriguing mystery in the stem cell field surrounding the

A new patent dispute has exploded in the stem cell field related to induced pluripotent stem (iPS) cells. What’s going on? In 2006, Shinya Yamanaka reported cellular reprogramming to create mouse induced pluripotent stem (iPS) cells in Cell and the next year multiple groups along with Yamanaka’s reported creating human iPS cells. It’s no exaggeration
