	CiteULike: Astrocytes secrete basal lamina after hemisection of rat spinal cord.
		Basal lamina is reconstructed over the lesioned surface of the spinal cord.
		Ultrastructurally (3 days), basal lamina was polymerizing as small projections on the surface of astrocytic membranes facing the lesion, endothelia or pia.
		By 5 days the basal lamina was a single membrane, folded multiple sheets or in swirls.

		In the renal glomeruli and the pulmonary alveoli, it is bounded by the lamina rara externa and the lamina rara interna.
		It consists of nine laminae (I–IX) that extend throughout the cord, roughly paralleling the dorsal and ventral columns of the gray substance, and a tenth region (lamina X) that surrounds the central canal and consists of the dorsal and ventral commissures and the central gelatinous substance.

	BBB association with pericytes, astrocytes and basal lamina (Site not responding. Last check: )
		The basal lamina surrounds the endothelial cells and pericytes; the region between which is known as the Virchow-Robin space.
		Between brain capillaries, astrocytes, and pericytes is the basal lamina, which consists of laminin, fibronectin, tenascin, collagens, and proteoglycan (Heimark, 1993).

	[No title]
		The basal lamina is a sheetlike structure, usually composed of type IV collagen, proteoglycan, and laminin, a glycoprotein that aids in binding cells to the basal lamina.
		Basal lamina components are contributed by the epithelial cells, the underlying connective tissue cells, and (in some locations) muscle, adipose, and Schwann cells.
		Basal laminae accompanied by reticular laminae are often thick enough to be seen with the light microscope as PAS- positive layers and are sometimes termed basement membranes, b.

	Epithelium
		In some cases the basal laminae are greatly thickened (as in the glomeruli and filtration system of the kidneys).
		The basal laminae, as seen by transmission electron microscopy, are seen to be formed from an electron-dense layer (50-80 nm thick) composed of non-fibrous type IV collagen and the proteoglycan, heparan sulfate, surrounded on both sides by a less-dense layer containing the glycoprotein, laminin.
		Basal laminae are not exclusive features of epithelia, but are also found associated with endothelia and some other cell types.

		The basal lamina is also able to determine cell polarity, influence cell metabolism, organise the proteins in adjacent plasma membranes, promote cell survival, proliferation or differentiation, and serve as specific highways for cell migration.
		The term basement membrane is often used to describe the basal lamina and this layer of collagen fibrils, although it isn’t strictly a membrane.
		The basal lamina is structured differently in different tissues, the lamina found on one side of endothelial cells forms a filter for regulating passage of proteins and molecules from the blood into tissues.

	Basal lamina - Wikipedia, the free encyclopedia
		The basal lamina is a component of the basement membrane that separates epithelium from the underlying connective tissue.
		The exception is when two epithelial layers abut one another as in the alveoli of the lungs and glomeruli of the kidneys, in which the basal lamina of one epithelial layer fuses with that of the other.
		The combination of the basal lamina and reticular lamina (or of two basal laminae) is called the basement membrane, a light microscopy term that predated the invention of the electron microscope.

		In short the basement membrane is comprised of the 3-layered basal lamina and the lamina fibroreticularis.

		Aging is associated with increased collagen type IV accumulation in the basal lamina of human cerebral microvessels
		The goal of this study was to evaluate age and hypertension related changes of the basal lamina in cerebral microvessels of individuals, who died from non-cerebral causes.
		Basal lamina changes of the cerebral microvessels were determined in the putamen using antibodies against collagen type IV and by quantitative analysis of vessel number, total stained area of collagen, thickness of the vessel wall and lumen, and relative staining intensity using immunofluorescence.

		The basal lamina (BL) is a specialised ECM found underlying epithelial cells: it coats muscle and fat cells, forms the glomerular filter in the kidney, and wraps the myelin sheath formed from Schwann cells on nerve axons.
		A specialised basal lamina forms the glomerular basement membrane, which is the filter of the kidney, and confers most of the filter's specificity: note the gaps between the epithelial and endothelial cells.
		Laminin is the pioneer of the basal lamina.

	Int. J. Dev. Biol. - Cellular origin of the basement membrane in embryonic chicken/quail chimeras. (Site not responding. Last check: )
		ABSTRACT The cellular origin of the components of the basal lamina of an epithelium, the chicken epiblast, has been investigated in a model system resulting from the transplantation of metabolically labeled quail hypoblast (an epithelium without basal lamina), associated or not with individual mesoblast cells, into an unlabeled chicken blastoderm deprived of its own hypoblast.
		The ability to discriminate chicken from quail cells after nuclear staining, combined with autoradiographic labeling of the basal lamina components, made it possible to determine the origin of the cells and labeled compounds in tissue sections of the chimeras.
		It is concluded that the basal lamina of the epiblast has a dual epithelial origin, resulting from the interaction of epiblast-derived materials and non-collagenous glycoproteins synthesized by the hypoblast.

	Epithelia
		The basement membrane, a structure seen with the light microscope, has been subdivided into a basal lamina (thought to be produced by the epithelium) and a reticular lamina (produced by connective tissue cells).
		Inspection of the epithelial layer at low-power indicates that the basal surface of the epithelium is indented by connective tissue papillae.
		The plasma membrane nearest the basement membrane is the basal membrane; the apical membrane lines the free surface, and the lateral membrane is between adjacent cells.

		Unfortunately, no studies on alterations of the different basal laminal components in diabetic peripheral nerves have been detailed enough to confirm whether there is an alteration in the proportions of the various components.
		Morphometric and morphological studies on human nerves suggest that the factors causing thickening of vascular basal lamina differ from those producing widened basal lamina in the perineurium.85 These studies suggested that the alterations in perineurial basal lamina were more characteristic of diabetic neuropathy than thickening of the basal laminal zone around endoneurial capillaries.
		Basal laminal changes of both perineurial cells and blood vessels differ from the Schwann cell basal laminal changes, where the abnormality is its abnormal shape and persistence during regeneration; on undamaged fibres it appears to be normal.
