OBJECTIVE To determine the role of bone morphogenetic proteins (BMPs) in stimulating glial scar formation in demyelinating lesions of the adult spinal cord. METHODS The dorsal columns of adult rats were injected with lysolecithin to induce a local demyelinating lesion. Levels of BMP4 and BMP7 proteins were assayed and compared with glial fibrillary acidic(More)
Oligodendrocyte precursors (OPCs) initially arise in the motor neuron domain of the ventral ventricular zone of the developing spinal cord. After dispersal throughout gray and white matter, OPCs differentiate in a characteristic ventral to dorsal sequence. The spatial localization of OPC induction is in part a result of both positive local sonic hedgehog(More)

By using time-lapse microcinematography, we recorded and conducted an analysis of the macrophage-like cell line MMC-1, including observations of the spreading, polarity, contact inhibition and mitosis common to cultured cells as well as the properties of phagocytosis and rosette formation unique to macrophage. We also found an MMC-1 cell which, after(More)

An HGPRT- cell line, CC-801AR2, was established from cloned human cervical carcinoma cell line CC-801 by using MNNG to induce cell mutation and 8-azaguanine (8-AG) to select the 8-AG resistant cells. The deficiency of HG-PRT in CC-801AR2 cells was proved by enzyme activity assay. This cell line was very sensitive to HAT medium. It was very similar in(More)

Human adrenal gland and aldosterone-producing adenoma (APA) obtained from adrenalectomy could be maintained in vitro for one to two months. The explants continued to secrete aldosterone for the duration of culture. This method was superior to monolayer cell culture. The influence of alpha-human atrial natriuretic factor (alpha-hANF) was investigated by(More)
