Cell Systems

Results We used stage-scanning OPM27,28 to perform light-sheet imaging of more than 65,000 WM266-4 melanoma cells embedded in a tissue-like collagen hydrogel (Figure 1A) that expressed a fluorescent marker of the membrane (CAAX-GFP), nucleus (histone-H2B), as well as an ERK kinase translocation reporter (ERK-KTR) (see STAR Methods). Cells were located in the gels in regions proximal to the coverslip and distal to the coverslip.

Keywords foundations of cell and developmental biology systems biology theoretical biology cell behavior tissue self-organization generative principles generality conceptual framework Introduction Cell and developmental biology aim to describe, understand, predict, and control the phenomena taking place in living systems at the mesoscopic scales between molecules and organisms.

Signaling pathways feature multiple interacting ligand and receptor variants, which are thought to act in a combinatorial manner to elicit different cellular responses. Transcriptome analyses now suggest that many signaling pathways use their components in combinations that are surprisingly often shared between otherwise dissimilar cell states.

Main text The embryo starts from a single fertilized egg and ends up with ∼400 cell phenotypes and approximately 100 types of tissues. 1 Vickaryous M.K. Hall B.K. Human cell type diversity, evolution, development, and classification with special reference to cells derived from the neural crest. The regularity of cell fate specification pushed the British embryologist Conrad Waddington to put forward the concept of an “epigenetic landscape.” 2 The Strategy of the Genes.

The microbiome functions that we aim to engineer emerge from a myriad of unknown and dynamic cellular interactions. These functions range from driving biogeochemical cycles in the environment to enabling colonization resistance to invading pathogens in host-associated microbiomes. Depending on the application, these functions can be major contributors to a process or significant minor contributors to a process.

Aberrant macrophage cytokine production is a conserved feature among autoimmune-prone mouse strains: elevated interleukin (IL)-12 and an imbalance in tumor necrosis factor-alpha and IL-10 define a unique cytokine profile in macrophages from young nonobese diabetic mice.
