Objectives- To isolate, culture-expand and differentiate mesenchymal stem cells from ovine bone marrow and determine their culture requirements for high expansion rate. Design- Experimental study. Animals- Five Shal sheep. Procedures- In this study, ovine marrow cells were plated and culture expanded through 3 successive subcultures. The resultant cells were then plated at differentiating condi...

Articular chondrocytes are known to be phenotypically unstable in culture. One condition that has been reported to suppress dedifferentiation is cultivation at high density on tissue-culture plastic. The aim of the experiments described here was to study the effect of seeding density on chondrocyte proliferation and 35SO4 incorporation, and on the types of collagen and proteoglycan synthesized....

Tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. On the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant E. coli, and consequently fed-batch culture have received less attention....

OBJECTIVES Loss of cardiac cells and the anatomical or functional remodeling of intercellular coupling occur under several pathological conditions. We have assessed the significance of intercellular coupling for cell death. METHODS AND RESULTS Ventricular cells obtained from 1 day old Wistar rats were cultured. Apoptosis was detected by nick-end labeling. Cells were plated at low and high cel...

BACKGROUND Monascus mycelia and pigments are promising sources of food and medicine with their potential pharmaceutical values and health-improving functions. Using high cell density fermentation of Monascus spp. to achieve higher mycelium and yellow pigment production is worthy to be researched. In this study, the characteristics and productivity shifting of pigments in high cell density cultu...
