PURPOSE To determine whether aqueous humor, the in vivo source of nutrients for trabecular meshwork cells, alters cellular and molecular characteristics in primary trabecular monolayer cell cultures when compared with standard culture conditions. METHODS Human primary trabecular meshwork cell cultures were grown in DMEM supplemented with 50% human aqueous humor (DMEM-AH), heat-denatured DMEM-...

Medium lacking serum but supplemented with milk will support the growth of sparse cells in culture. Milk obtained within 8 h after the birth of a calf (day 1 colostrum) is the most effective in supporting proliferation. In mixed cultures of early-passage bovine embryonic kidney (BEK) or early-passage calf kidney (CK) cells, both epithelial cells and fibroblasts grow in Dulbecco's modified eagle...

Unraveling the mechanisms behind the processes of cell attachment and the enhanced proliferation that occurs as a response to the presence of calcium silicate-based materials needs to be better understood so as to expand the applications of silicate-based materials. Ions in the environment may influence apatite precipitation and affect silicate ion release from silicate-based materials. Thus, t...

Macrophages play an important role in immune and inflammatory responses, and have been extensively studied in vitro using culture media such as RPMI1640 medium, Dulbecco's modified Eagle medium (DMEM), and Ham's F-12 medium (F-12). We found that the activation phenotypes of a murine macrophage-like cell line, J774.1/JA-4, were obviously different in two distinct culture media (F-12 and DMEM), b...

METHODS. Rhesus monkey keratocytes were isolated from central corneal buttons by collagenase digestion for 16 hours, seeded on plastic in Dulbecco’s modified Eagle’s medium (DMEM) containing insulin-transferrin-sodium selenite (ITS) supplement (DMEM/ITS) or 10% fetal bovine serum (DMEM/ 10% FBS), or in a defined keratinocyte serum-free medium (KSFM). After confluence, cells in KSFM were continu...

Thermal balneotherapy with Comano spa's water (CW; Trentino, Italy) is used for psoriasis and other skin disorders but the mechanism(s) of action of this hypotonic water are unknown. Since skin psoriatic manifestations are thought to be angiogenesis-dependent, we assessed CW's effects on the expression and release of VEGF-A protein isoforms by cultured human lesional keratinocytes isolated from...

PURPOSE Selenite-induced cataract is associated with oxidative stress, loss of calcium homeostasis, activation of calpain enzymes, and apoptotic cell death in the lens. An evaluation of naturally occurring antioxidants that also restrict calcium influx into the lens and calpain activation and thus prevent lenticular cell death may lead to the development of safe and effective anticataractogenic...
