An antiserum against basic fibroblast growth factor was characterized by immunoblot experiments and used to investigate immunohistochemically the projection fields and fine structures of basic fibroblast growth factor-containing cerebellar Purkinje cells. The antiserum demonstrated clearly purified basic fibroblast growth factor and basic fibroblast growth factor-like molecules of the same molecular weight in homogenates of the adult rat cerebellum. Light and electron microscopic immunohistochemistry revealed that a large number of Purkinje cells, if not all, send immunoreactive dendrites to the molecular layer and basic fibroblast growth factor-containing axons to the deep cerebellar and lateral vestibular nuclei, where basic fibroblast growth factor nerve terminals form synapses with the soma and dendrites of neurons labeled weakly with basic fibroblast growth factor. Nerve cells with basic fibroblast growth factor had immunoreaction deposits mainly in free ribosomes, those attached to the endoplasmic reticulum and in the nuclear euchromatin. These findings suggest that basic fibroblast growth factor is present in cerebellar Purkinje cells and undergoes two modes of transport, one to axon terminals and the other to nuclear euchromatin, known as the RNA transcription zone.

D009411	Nerve Endings	Branch-like terminations of NERVE FIBERS, sensory or motor NEURONS. Endings of sensory neurons are the beginnings of afferent pathway to the CENTRAL NERVOUS SYSTEM. Endings of motor neurons are the terminals of axons at the muscle cells. Nerve endings which release neurotransmitters are called PRESYNAPTIC TERMINALS.	Ending, Nerve,Endings, Nerve,Nerve Ending

D002531	Cerebellum	The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills.	Cerebella,Corpus Cerebelli,Parencephalon,Cerebellums,Parencephalons
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001369	Axons	Nerve fibers that are capable of rapidly conducting impulses away from the neuron cell body.	Axon
D015151	Immunoblotting	Immunologic method used for detecting or quantifying immunoreactive substances. The substance is identified by first immobilizing it by blotting onto a membrane and then tagging it with labeled antibodies.

D016222	Fibroblast Growth Factor 2	A single-chain polypeptide growth factor that plays a significant role in the process of WOUND HEALING and is a potent inducer of PHYSIOLOGIC ANGIOGENESIS. Several different forms of the human protein exist ranging from 18-24 kDa in size due to the use of alternative start sites within the fgf-2 gene. It has a 55 percent amino acid residue identity to FIBROBLAST GROWTH FACTOR 1 and has potent heparin-binding activity. The growth factor is an extremely potent inducer of DNA synthesis in a variety of cell types from mesoderm and neuroectoderm lineages. It was originally named basic fibroblast growth factor based upon its chemical properties and to distinguish it from acidic fibroblast growth factor (FIBROBLAST GROWTH FACTOR 1).
