Isolation, Culture and Differentiation of Buffaloes Bone Marrow Mesenchymal Stem Cells Obtained from the Coxal Tuberosity

Currently, much attention has been devoted to the renewal of knowledge about Stem Cells and Cell Therapy in domestic species. In this sense, the present work aimed to develop a methodology for collecting, processing and cultivation of mesenchymal stem cells obtained from bone marrow of coxal tuberosity in buffaloes. The collection was performed using a Komiyashiki needle, which was introduced in the coxal tuberosity and the bone marrow aspirated into a heparinized syringe with the aid of negative pressure. Directly after collection samples were processed at the laboratory at FMVZ - UNESP. The samples took approximately 32 days to reach 80% confluence, when the first passage and differentiation was performed. To confirm the mesenchymal origin, cells were induced to differentiate into adipogenic and osteogenic lineages. Samples showed morphological changes during differentiation protocol, but not all presented production of extracellular deposits of calcium or intracellular fat droplets, observed after staining with Alizarin Red and Oil Red respectively. Compared with the material obtained from other species and processed in the same laboratory, the primary culture was longer. Therefore, more studies are needed to standardize the age of animals used and to test other inducers of cell differentiation.

The community-level effect of light on germination timing in relation to seed mass: a source of regeneration niche differentiation

Within a community, species may germinate at different times so as to mitigate competition and to take advantage of different aspects of the seasonal environment (temporal niche differentiation). We illustrated a hypothesis of the combined effects of abiotic and biotic competitive factors on germination timing and the subsequent upscale effects on community assembly. We estimated the germination timing (GT) for 476 angiosperm species of the eastern Tibetan Plateau grasslands under two light treatments in the field: high (i.e. natural) light and low light. We also measured the shift in germination timing (SGT) across treatments for all species. Furthermore, we used phylogenetic comparative methods to test if GT and SGT were associated with seed mass, an important factor in competitive interactions. We found a significant positive correlation between GT and seed mass in both light treatments. Additionally, small seeds (early germinating seeds) tended to germinate later and large seeds (late germinating seeds) tended to germinate earlier under low light vs high light conditions. Low light availability can reduce temporal niche differentiation by increasing the overlap in germination time between small and large seeds. In turn, reduced temporal niche differentiation may increase competition in the process of community assembly.
