Cellular differentiation in the shoot epidermis
Current Opinion in Plant Biology, 1998The recent advances in defining genes involved in shoot epidermal cell differentiation are impressive, especially the characterisation of genes involved in cellular patterning. The additional influences of environment and hormones on cellular patterning have recently been emphasised, and important connections have been made to changes in vegetative and

Cellular differentiation and the microcompartmentation of glycolysis
Mechanisms of Ageing and Development, 1991In this paper, the main features of the cellular activities of the glycolytic enzymes during growth and tissue differentiation are summarized, and correlated with the occurrence of multiple forms of these enzymes, and with their degree of interaction with subcellular structure.

Differentiation, oncogenesis and cellular periodicities
Journal of Theoretical Biology, 1968Abstract An outline is given of a concept of differentiation and oncogenesis which is based on the existence of cellular biochemical periodicities. It is proposed that the properties of a cell are largely determined by the pattern of rhythmic variations in constituent levels resulting from the operation of numerous metabolic control circuits.

Maintaining differentiated cellular identity
Nature Reviews Genetics, 2012Various studies have demonstrated that somatic differentiated cells can be reprogrammed into other differentiated states or into pluripotency, thus showing that the differentiated cellular state is not irreversible. These findings have generated intense interest in the process of reprogramming and in mechanisms that govern the pluripotent state ...

TUMOURS, HORMONES, AND CELLULAR DIFFERENTIATION
The Lancet, 1969Abstract The " ectopic " production of hormones by tumours is set in the wider context of structural and functional metaplasia and considered in relation to the control of cell structure and function by D.N.A. The association of hormone production with certain specific tumour types and not with others, best shown for corticotrophin, is not consistent

mRNA STABILITY AND CELLULAR DIFFERENTIATION
Acta Endocrinologica, 1972ABSTRACT The diversity of mRNA half-lives was investigated in a differentiated insect tissue, the silkmoth galea, which is specialized for production of a characteristic protein, the zymogen of the proteolytic enzyme, cocoonase. It appears that the differentiation-specific cocoonase mRNA is uniquely stable (half-life ca. 100 h).

Cellular differentiation and morphogenesis in Cordylophora
Wilhelm Roux' Archiv f�r Entwicklungsmechanik der Organismen, 1969The interstitial cells ofCordylophora were destroyed by treating animals with 4,500 Roentgens of x-irradiation. Within 5-6 days after treatment no interstitial cells were detected in the treated animals and they were never seen in later stages. Some cell divisions were noted in the epidermal epithelio-muscular cells of the x-rayed animals which ...

ON THE CHROMOSOMAL BASIS FOR CELLULAR DIFFERENTIATION
American Journal of Botany, 1965The relationship of somatic polyploidy to cellular differentiation is discussed. Evidences for the occurrence of endopolyploidy on the basis of auxin‐induced divisions are questioned and considered valid in the light of radioisotope studies of DNA synthesis. The non‐universality of endopolyploidy is shown by known exceptions.

Cellular differentiation in the anuran pronephros
The Anatomical Record, 1963AbstractRibonucleic acid (RNA) is detectable histochemically by means of methyl green pyronin staining (controlled with ribonuclease) in the cytoplasm of the proximal tubules of the frog (Rana pipiens). This is seen at Shumway stage 23 when the proximal tubules become differentiated from the remainder of the tubular complex.

A role for cadherins in cellular signaling and differentiation
Journal of Cellular Biochemistry, 1998Cadherins form a family of cell-cell adhesion proteins that are critical to normal embryonic development. Expression of the various family members is regulated in a complex pattern during embryogenesis. Both reduced and inappropriate expression of cadherins have been associated with abnormal tissue formation in embryos and tumorigenesis in mature ...
