Cell length, cell growth and cell division
Nature, 1976When cells of E. coli reach a certain critical length, which is constant in all growth conditions and eqqal to twice the minimum cell length, they abruptly increase their rate of elongation and divide about 20 min later. Chromosome replication terminates at about this same cell length but is not the signal for the change in rate of cell elongation.

The recent advances in molecular biology and genetics, as well as the progress of in vitro techniques, have provided a more coherent image of the thymic function on the molecular level. But they have shifted the attention away from studies on the cellular level, which are necessary to clarify the biological roles of different cell types of the thymic ...

A major feature in Dictyostelium development is the transition from the unicellular to the multicellular stage, a process brought about by chemotaxis and cell-cell adhesion. Growth-phase cells are weakly cohesive, whereas aggregation-competent cells adhere strongly to each other.

Stromal Cell–Immune Cell Interactions
Annual Review of Immunology, 2011Interaction between different types of hematopoietic cells is essential for proper functioning of the immune system. For instance, the cytokines produced by antigen-presenting dendritic cells will determine the type of T cell response that is induced.

Gene therapy based on the use of viral vectors is entirely dependent on the use of animal cell lines, mainly of mammalian origin, but also of insect origin. As for any biotechnology product for clinical use, viral -vectors have to be produced with cells derived from an extensively characterized cell bank to maintain the appropriate standard for ...

Many physicians and patients do not believe that dermatology involves life-threatening situations; however, there are many emergencies that the dermatologist needs to address, and many cutaneous diseases in the emergency room that require rapid dermatologic consultation.

Cell-cell contacts specify cell fate
Science, 2020Developmental Biology Ascidians, or sea squirts, are marine invertebrate filter feeders with highly reproducible cellular events and invariant embryonic cell lineages. Guignard et al. studied the ascidian embryo to address the determinants of this cellular reproducibility.

Cell Division, Cell Growth, Cell Differentiation
2009The basis of growth and development of all biological systems is cellular growth, cell division, and cell differentiation. Using cell and tissue culture opens up possibilities to investigate influences of nutrients and growth regulators on each of these phenomena, without confounding effects of remote tissue, as would be the case when using intact ...

Current Opinion in Hematology, 1998
Dendritic cells are potent stimulators of immune responses against foreign antigens. Recent advances in this area include the delineation of distinct developmental pathways for different dendritic cell subsets; the emerging concept that one dendritic cell subset has regulatory functions that may contribute to induction of tolerance to self antigens ...
