Modulation of a single amino acid in the reprogramming factor Kruppel-like factor 4 (KLF4) has been demonstrated to markedly improve natural transcription factor function and to result in faster and more effective reprogramming of somatic cells into induced pluripotent stem cells.

A group of scientists at the Cincinnati Children's Hospital has used separate lines of human induced pluripotent stem cells to create stomach organoids with a three-layered structure and gastric function such as smooth muscle contraction and glandular secretion. The team reported its results in the December 2021, issue of Cell Stem Cell.

Clade Therapeutics Inc., which launched with an $87 million series A round, may have what sounds like an ambitious goal: to create scalable, off-the-shelf stem cell-based medicines that can be as accessible to patients as antibody therapies are today. But the startup, backed by more than two decades of advances in the area of induced pluripotent stem cells, is within sight of developing a cell therapy to take into clinical testing.

DUBLIN – Treefrog Therapeutics SA closed a $75 million series B round this week, which will help to increase its reach and its profile, as it pursues its highly ambitious objective to drive the adoption of a new way of making induced pluripotent stem cells (iPSCs) at scale. The Bordeaux, France-based firm is not a CDMO in any sense, however. It is a fully fledged biotech, with early stage iPSC-based programs in Parkinson’s disease, cardiovascular disease and bone marrow transplant, among others. It’s just that it is also attempting to revolutionize how those cells are cultivated before it administers them as therapies.

Barely a week after cutting a deal with Beigene Ltd. that included an up-front of $45 million cash, Shoreline Biosciences Inc. and Gilead Sciences Inc.-owned Kite are collaborating to develop allogeneic cell therapies in a deal that could bring Shoreline more than $2.3 billion plus royalties.

LONDON – The alchemy of induced pluripotent cells has broken another barrier, delivering a model of the earliest preimplantation stages of human development, when fertilized eggs form a blastocyst.

DUBLIN – Cellectis SA is picking up $15 million worth of equity in Cytovia Therapeutics Inc. and could earn as much as $760 million in development, regulatory and sales milestones from a deal involving up to five gene-edited allogeneic natural killer (NK) cell or chimeric antigen receptor (CAR-NK) cell therapies employing its Talen (transcription activator-like effector nuclease) gene editing technology.

PERTH, Australia – Melbourne-based regenerative medicine company Cynata Therapeutics Ltd. is gearing up to take its Cymerus mesenchymal stem cell (MSC) product candidate, CYP-004, into a phase III trial in osteoarthritis.

Aspen Neuroscience Inc. hopes to get into the clinic to test autologous neuron replacement in Parkinson’s disease with a $6.5 million seed round. The financing featured several established life sciences venture investors; it was led by Domain Associates and Axon Ventures and included Alexandria Venture Investments, Arch Venture Partners, Orbimed, and Section 32.
