Objective- To evaluate the potential effects of uncultured adipose derived stromal vascular fraction on tendon healing. Design- Prospective descriptive study. Animals- Twenty five adult male New Zealand white rabbits, weighing 2.5-3.0 kg were used. Five rabbits were used as donors of adipose tissue and the rest were divided into control and treatment groups. Procedures- The injury model was ...

Reactive stroma has been reported in many cancers, including breast, colon, and prostate. Although changes in stromal cell phenotype and extracellular matrix have been reported, specific mechanisms of how reactive stroma affects tumor progression are not understood. To address the role of stromal cells in differential regulation of tumor incidence, growth rate, and angiogenesis, LNCaP xenograft...

Stromal cells from DBA/2 mouse bone marrow have been shown to be susceptible to cytotoxicity induced by several redox-active metabolites of benzene, including hydroquinone (HQ). Treatment with HQ also alters the composition of stromal cell populations by preferentially killing stromal macrophages compared to stromal fibroblasts. This cytotoxicity can be prevented by 1,2-dithiole-3-thione (DTT) ...

The endometrial stromal nodule is a benign tumor composed of differentiated endometrial stromal cells arranged as a well circumscribed nodule with smooth non-invasive margins. They are rare neoplasms, diagnosed in most instances by microscopy. Although nodules are benign in nature, hysterectomy is the treatment of choice to enable evaluation of the tumor margins which are well demarcated in...

Secondary lymphoid organs including lymph nodes are composed of stromal cells that provide a structural environment for homeostasis, activation and differentiation of lymphocytes. Various stromal cell subsets have been identified by the expression of the adhesion molecule CD31 and glycoprotein podoplanin (gp38), T zone reticular cells or fibroblastic reticular cells, lymphatic endothelial cells...

Precursor cells of the B lineage can be enriched from mouse fetal liver by FACS with the aid of the pre-B cell-specific mAb G-5-2. The cells are concomitantly enriched for cells expressing the pre-B cell-specific gene lambda 5, and for cells developing to LPS-reactive mature B cells. The enriched purified precursors are not influenced by rIL-2 through -7, alone or in combination, to develop to ...

Cancer cell collective migration is a complex behaviour leading to the invasion of cancer cells into surrounding tissue, often with the aid of stromal cells in the microenvironment, such as macrophages or fibroblasts. Although tumour-tumour and tumour-stromal intercellular signalling have been shown to contribute to cancer cell migration, we lack a fundamental theoretical understanding of how a...

The chemokine stromal cell-derived factor-1 (SDF-1) is constitutively expressed by bone marrow stromal cells and plays key roles in hematopoiesis. Fibroblast growth factor 2 (FGF2), a member of the FGF family that plays important roles in developmental morphogenic processes, is abnormally elevated in the bone marrow from patients with clonal myeloid disorders and other disorders where normal he...

The chemokine stromal cell–derived factor-1 (SDF-1) is constitutively expressed by bone marrow stromal cells and plays key roles in hematopoiesis. Fibroblast growth factor 2 (FGF2), a member of the FGF family that plays important roles in developmental morphogenic processes, is abnormally elevated in the bone marrow from patients with clonal myeloid disorders and other disorders where normal he...

B lymphocyte precursor cells in mouse bone marrow develop in close association with stromal cells which provide essential growth signals. To identify molecules that may normally play a role in this interaction we have examined the in vivo binding of a new monoclonal antibody (mAb) (KMI6) that recognizes a determinant on a bone marrow stromal cell line (BMS2) in vitro. Flow cytometric and radioa...
