Mice that are homozygous for the recessive osteopetrosis spontaneous mutation (op/op) develop severe osteopetrosis due to a defect in the production of macrophage colony-stimulating factor (M-CSF) and a deficiency in monocyte-derived osteoclasts. Our study describes a novel soft tissue finding in an osteopetrosis (B6C3Fe a/a-Csf1(op)/J) mouse model. Tissues were obtained from B6C3Fe a/a-Csf1(op...

Edematous syndrome is quite common in modern clinical practice. Swelling one of the most complaints that cause patient to consult a doctor and often become first manifestation many diseases. Fluid makes up approximately 3/5 human body weight, 70% which located cells, about 30% extracellular. There constant exchange electrolytes other substances involved metabolism between cell extracellular flu...

Integration of muscle, connective tissue and skeletal patterning during development is essential for proper functioning of the musculoskeletal system. How this integration is achieved is poorly understood. There is ample evidence suggesting that skeletal pattern is programmed autonomously, whereas muscle pattern is, for the most part, programmed non-cell-autonomously. Connective tissues depend ...

From the ocular connective tissues, relatively pure structural glycoproteins (SGP) are extractable by means of 8 m urea after trichloroacetic acid treatment. The SGP from corneal stroma (CSGP) and from sclera (SSGP) show considerable immunochemical similarities and are not related to SGP from anterior lens capsule (LSGP). An antiserum directed against the total connective tissue fraction of cor...

The biomechanical properties of connective tissues play fundamental roles in how mechanical interactions of the body with its environment produce physical forces at the cellular level. It is now recognized that mechanical interactions between cells and the extracellular matrix (ECM) have major regulatory effects on cellular physiology and cell-cycle kinetics that can lead to the reorganization ...

Dermatophyte infections are one of the most common superficial fungal infections. However dermatophytes invade subcutaneous tissues rarely. We report herein a 65 year-old woman who was as a known case of rheumatoid arthritis (For 10 years) and taking immunosuppressive drugs, presented with multiple nodules and sinuses in the knee area. Histopathologic studies revealed PAS positive granulomas an...

Hyaluronan (HA), an important component of connective tissues, is highly metabolically active, but the mechanisms involved in its catabolism are still largely unknown. We hypothesized that a protein similar to sperm PH-20, the only mammalian hyaluronidase known to be active at neutral pH, could be expressed in connective tissue cells. An mRNA transcript similar to that of PH-20 was found in cho...
