Neuronal differentiation in the Drosophila ommatidium

Developmental Biology, 1987
Using monoclonal and polyclonal antibodies as differentiation markers, we have found that the eight photoreceptors of the Drosophila ommatidium differentiate in a fixed sequence. The foundation photoreceptor, R8, expresses neural antigens first. The paired photoreceptors R2/5 are next to express, followed by the pair R3/4, followed by the pair R1/6; R7

Neuronal nitric oxide synthase expression in neuronal cell differentiation

Neuroscience Letters, 1996
Expression of neuronal nitric oxide synthase (n-NOS) was investigated during neuronal cell differentiation. Trace amounts of n-NOS mRNA were detected in the primary culture of neural precursor cell (NPC) at embryonic day 10, and a high level of n-NOS mRNA was observed after a further 7 days cultivation of NPC.

Differentiation of Cochlear Afferent Neurons

Acta Oto-Laryngologica, 1981
In order to clarify some open questions, the various types of afferent neurons of the cochlea were analysed in various species regarding their structural features, their association with outer or inner hair cells and their connection to the CNS, by means of degeneration experiments and tracer studies.

Drosophila Neuron Differentiation in Vitro

1971
Many investigators have described the growth of axons in vitro from explants of embryonic mammalian or bird tissue (Murray, 1965). In all cases the explant contained cells from already differentiated nervous tissue and no claims were made for neuron differentiation from stem cells.

Acetylcholine synthesis and neuron differentiation.

The International journal of developmental biology, 2000
Development of the nervous system is dependent on the co-operation between cell determination events and the action of epigenetic factors; in addition to well known factors, e.g. growth factors, neurotransmitters have been assigned a role as "morphogens" and modulators of neuronal differentiation in an early developmental phase.

Role of Phosphatidylcholine during Neuronal differentiation

IUBMB Life, 2011
Neuronal differentiation is characterized by neuritogenesis and neurite outgrowth, processes, which are critically dependent on membrane biosynthesis, and therefore, on the expression and regulation of enzymes involved in phospholipid biosynthesis. During the last decade a great effort was made to clarify where membrane lipids are synthesized, how the ...

Neuronal Differentiation and Synaptogenesis in Retinoblastoma

Cancer Research, 2007
Abstract Retinoblastomas initiate in the developing retina in utero and are diagnosed during the first few years of life. We have recently generated a series of knockout mouse models of retinoblastoma that recapitulate the timing, location, and progression of human retinoblastoma.

Signal transduction pathways in neuronal differentiation

Current Opinion in Neurobiology, 1993
New insights into the signal transduction pathways for neuronal growth factors and cell adhesion molecules are affording us a better understanding of the intracellular mechanisms for neuronal differentiation, and of the ways in which the various signals are integrated during this process.

Prenatal differentiation of mouse vomeronasal neurones

European Journal of Neuroscience, 1998
AbstractThe vomeronasal organ (VNO) subserves basic chemosensory functions in rodents, mainly related to sexual behaviour. In order to understand early stages of the VNO structural maturation, we have undertaken an immunocytochemical analysis of the VNO of fetal mice.

Cytokines and neuronal differentiation.

Critical reviews in neurobiology, 1996
A diverse spectrum of complementary experimental investigations has demonstrated that two major cytokine superfamilies, the transforming growth factor-beta (TGF beta) and the hemopoietins, mediate an extensive range of developmental events in the nervous system that often rivals and frequently exceeds that of the classic neurotrophins.
