Cancer cells fused with macrophages exhibit enhanced adhesive strength, formed tumors more rapidly than unfused cancer cells and flourished under conditions that dramatically inhibited growth of unfused cancer cells Cancer cells that spontaneously fuse with macrophages, the immune system's healthy scavenger cells, play a key role in the metastasis, or spread of the cancer to other areas of the body, according to research to be presented Sunday, Dec. 15, at the American Society for Cell...

A research team led by Professor Noriyuki Tsumaki of the Center for iPS Cell Research and Application (CiRA) at Kyoto University and Dr. Hidetatsu Ohtani, a former CiRA member who now works as a post doctoral fellow at Osaka University Graduate School of Medicine, has succeeded in directly converting human dermal fibroblasts into induced chondrogenic cells (iChon cells) without passing through an iPS cell stage in a process known as direct reprogramming. This finding has been published in...

Fat progenitor cells may contribute to cancer growth by fortifying the vessels that provide needed blood to tumors, according to preclinical research findings by investigators at The University of Texas Health Science Center at Houston (UTHealth). The results were reported in Cancer Research, a journal of the American Association for Cancer Research. Studies of groups of people have demonstrated a link between obesity and certain cancers; however, the physiological causes have not been...

American Cancer Society-Funded Research Reveals Molecule Called Cadherin-23 Could Play a Role in the Earliest Stages of Breast Cancer Rensselaer Polytechnic Institute Biologist Lee Ligon has found a previously unknown connection between breast cancer tumor cells and the surrounding healthy tissue. The results provide new information on the earliest stages of breast cancer metastasis. The results were published March 7, 2012, in the journal PLoS One, in a paper titled “ Cadherin-23...

Fibroblasts, cells that play a role in the structural framework of tissues, play an apparent role in melanoma tumor growth. Fibroblasts also contribute to melanoma drug resistance and may also facilitate the "flare" response when a tumor's metabolism is enhanced following a patient being removed from a targeted therapy, said researchers at Moffitt Cancer Center in Tampa, Fla. Alexander R. Anderson, Ph.D., co-director of Integrative Mathematical Oncology at Moffitt, and Moffitt...

Stromal cells, as distinct from hematopoietic cells, are an essential component of the bone marrow microenvironment and are necessary for the long-term maintenance of hematopoietic stem cells (HSCs) in vitro. Previous studies have shown that stromal cells regulate the proliferation and differentiation of HSCs through the production of diffusible hematopoietic regulatory factors and extracellular matrix, and through physical cell-cell interactions involving adhesion molecules and gap...

A fibroblast is not always just a fibroblast "“ particularly in the heart. In a heart attack, fibroblasts "“ special repair cells that form a scar after injury "“ come from a population of stem cells that reside within the heart, said researchers from Baylor College of Medicine and the Methodist Hospital in a report that appears in the journal Cardiovascular Research. By contrast, earlier work showed that the fibroblasts responsible for fibrosis "“ excess fibrous...

While some scientists have argued that cancer is such a complex genetic disease that you'd have to sequence a person's complete genome in order to predict his or her cancer risk, a University of California, Berkeley, cell biologist suggests that the risk may be more simply determined by inexpensively culturing a few skin cells. Harry Rubin, professor emeritus of molecular and cell biology at UC Berkeley, acknowledges that cancer cells have mutations in hundreds of genes, making it hard to...
