Researchers have created a new model to study germ cell tumors in testes by transplanting embryonic stem cells into mouse models. The resulting tumors mimic the early stages of tumor development and offer valuable insights into the genetic regulation of these cancers. This approach has potential applications for developing novel therap...

Study finds cryopreserved endothelial progenitor cells phenotypically identical to non-frozen

A study published in Cell Transplantation found that cryopreserved endothelial progenitor cells have the same phenotypic, structural, and functional properties as non-frozen cells. This discovery eliminates the need for cell isolation procedures before using these cells in clinical transplantation.

Establishing the first line of human embryonic stem cells in Brazil

A Brazilian research team successfully established the first line of human embryonic stem cells (hES), but struggled to find a genetically diverse match for the diverse ethnic and genetic Brazilian population. The researchers overcame legal and ethical guidelines to create hES cell line BR-1, which is mostly European in origin.

Umbilical cord blood-derived stem cells studied for lupus therapy

Researchers found that umbilical cord blood-derived mensenchymal stem cells (uMSCs) can delay renal function deterioration and alleviate symptoms of lupus nephritis. Early transplantation with allogenic MSCs showed the most promising results, supporting their potential use in treating systemic lupus erythematosus.

Trapping prostate cancer cells to keep them from spreading provides hope

Trapping prostate cancer stem cells with self-assembling nanomaterials inhibits colony formation and cell division in vitro. The approach may offer a new treatment strategy for metastatic hormone-refractory prostate cancer by targeting cancer stem cells, which are thought to be the origin of tumor metastasis.

Transplanting umbilical cord and menstrual blood-derived stem cells offer hope for disorders

Researchers have found that stem cells derived from umbilical cord blood cells and menstrual blood may offer therapeutic benefits for disorders such as stroke, Alzheimer's disease, and amyotrophic lateral sclerosis (ALS). These cells can differentiate into various types of cells and have anti-inflammatory properties.

Human umbilical cord blood cells aid diabetic wound healing

Researchers found that transplanted EPCs from human umbilical cord blood significantly accelerated wound closure in diabetic mouse models. The study showed that growth factors and cytokines produced at the wounded skin sites contributed to healing. This experimental study opens the possibility of using endothelial progenitor cells deri...

Fat cells become useful stem cells in tissue reconstruction

Researchers have isolated and characterized adult fat cell-derived stem cells, which maintain their stem cell characteristics and could aid in tissue regeneration. The study's findings suggest that these cells may be useful for cell-based therapies and represent a promising area of research for plastic surgery applications.
