UWM researcher makes breakthrough in stem cell technology

UW-Milwaukee researcher Andrew Cohen has successfully developed a software program that facilitates predicting the evolution of stem cells. The program essentially speeds up what has been a tedious process for researchers in the past.

The program was published last week in the journal Nature Methods. It applies algorithmic information theory to the growth and movement of stem cells tracked over time to show what type of cells (i.e. brain, skin, etc.) they will eventually develop into.

“People look at images and take measurements by hand,” Cohen explained. “It takes a long time, and using computers makes the process a

POTENTIAL NEW “TWIST” IN BREAST CANCER DETECTION

December 4, 2009- Working with mice, scientists at Johns Hopkins publishing in the December issue of Neoplasia have shown that a protein made by a gene called “Twist” may be the proverbial red flag that can accurately distinguish stem cells that drive aggressive, metastatic breast cancer from other breast cancer cells.

Building on recent work suggesting that it is a relatively rare subgroup of stem cells in breast tumors that drives breast cancer, scientists have surmised that this subgroup of cells must have some very distinctive qualities and characteristics.

KOLKATA – Cancer patient gets stem cell transplant

A team of doctors of haematology department of Nilratan Sircar Medical College and Hospital performed a blood stem cell transplantation on a patient wherein they successfully re-infused blood stem cells into a patient’s bloodstream on 30 January. The patient is suffering from a type of blood cancer known as multiple myeloma.
Mrs Bela Samanta, a resident of Burdwan, has been a patient of leukaemia for past one year. On 16 December she was admitted to the hospital in a critical condition. Doctors examined her and said there was a need for this transplantation, if the patient wanted to lead a

MultiCell teams with Maxim Biotech to study live stem cells and cancer

Rhode Island-based biotechnology company MultiCell Technologies Inc. is teaming up with Maxim Biotech Inc. under cooperative research and development agreement to develop products for studying liver stem cells and liver cancer.

MultiCell (OTC: MCET), based in Woonsocket, owns exclusive rights to two issued U.S. patents, one U.S. patent application and a handful of corresponding foreign patents and patent applications regarding the isolation and differentiation of liver stem cells.

No financial details of the agreement with South San Francisco-based Maxim Biotech were disclosed. The deal will initially focus on creating a family of research reagent tool kits which can be used to

STEM CELLS BATTLE FOR SPACE

The body is a battle zone. Cells constantly compete with one another for space and dominance. Though the manner in which some cells win this competition is well known to be the survival of the fittest, how stem cells duke it out for space and survival is not as clear. A study on fruit flies published in the October 2 issue of Science by Johns Hopkins researchers describes how stem cells win this battle by literally sticking around.

“Our work exemplifies how one signal coordinately maintains two types of stem cells in a single niche, or microenvironment,” says Erika Matunis,
