"Intermediate" Cell Types and Mixed Cell Proliferation in Multiple Myeloma: Electron Microscopic Observations

"Intermediate" cell types and mixed cell proliferation in multiple myeloma: electron microscopic observations.

CD28-mediated regulation of multiple myeloma cell proliferation and survival.

Although interactions with bone marrow stromal cells are essential for multiple myeloma (MM) cell survival, the specific molecular and cellular elements involved are largely unknown, due in large part to the complexity of the bone marrow microenvironment itself. The T-cell costimulatory receptor CD28 is also expressed on normal and malignant plasma cells, and CD28 expression in MM correlates si...

a patient with multiple myeloma and renal cell carcinoma

the coexistence of two malignancies is rarely seen. a little association between hematologic malignancies especially multiple myeloma and renal cell carcinoma has been reported in the recent past. several case series revealed a bidirectional association between these two malignancies which may be due to the common risk factors, similar cytokine growth requirements and clinical presentation. her...

Multiple myeloma cell-derived microvesicles are enriched in CD147 expression and enhance tumor cell proliferation

Multiple myeloma (MM) is characterized by the clonal expansion of malignant plasma cells within the bone marrow. There is a growing literature that tumor cells release biologically active microvesicles (MVs) that modify both local and distant microenvironments. In this study, our goals were to determine if MM cells release MVs, and if so, begin to characterize their biologic activity. Herein we...

Cdk4 functions in multiple cell types to control Drosophila intestinal stem cell proliferation and differentiation

The proliferation of intestinal stem cells (ISCs) and differentiation of enteroblasts to form mature enteroendocrine cells and enterocytes in the Drosophila intestinal epithelium must be tightly regulated to maintain homeostasis. We show that genetic modulation of CyclinD/Cdk4 activity or mTOR-dependent signalling cell-autonomously regulates enterocyte growth, which influences ISC proliferation...
