Establishment of shape during embryonic development, and the maintenance of shape
against injury or tumorigenesis, requires constant coordination of cell behaviors toward the …

Twenty years ago, we proposed a model of developmental control based on tensegrity
architecture, in which tissue pattern formation in the embryo is controlled through …

Force production and the propagation of stress and strain within embryos and organisms are
crucial physical processes that direct morphogenesis. In addition, there is mounting …

Direct knowledge of Ca2+ patterns in vertebrate development is largely restricted to early
stages, in which they control fertilization, ooplasmic segregation and cleavage. To explore …

A common reductionist assumption is that macro-scale behaviors can be described “bottom-
up” if only sufficient details about lower-scale processes are available. The view that an …

The sha** of the early embryo requires pattern formation as well as geometric and
topological morphogenesis of the develo** tissues. The morphogenetic movements that …

The greatest mystery of life is how a single fertilized egg develops into a fully functioning,
sometimes conscious multicellular organism. Embryogenesis Explained offers a new theory …

Circadian rhythms refer to oscillations in biological processes with a period of approximately
24 h. In addition to the sleep/wake cycle, there are circadian rhythms in metabolism, body …

Pattern formation of biological structures involves the arrangement of different types of cells
in an ordered spatial configuration. In this study, we investigate the mechanism of patterning …

This survey focuses on early or primitive developmental phenomena for which the location
of a steady high calcium region or the direction of a calcium wave is critical and calcium is …
