		The mid-dle incisural space is a narrow cleft between the upper brainstem medially, at the level of the pontomesencephalic junction, and the medial aspect of the temporal lobe, namely the parahippocampal gyrus.
		It corresponds to the ambient and crural cisterns.
		The part of the middle incisural space exposed by this approach corresponds to the trigonum lemnisci and to the segment (area) of the cerebellomesencephalic fissure occupied by the superior cerebellar peduncle and by the dorsal portion of the middle cerebellar peduncle.

	Distribution of protein disulfide isomerase in rat epiphyseal chondrocytes. (Site not responding. Last check: 2007-10-30)
		The labeling density of the cisternal space of the dilated ER, probably reflecting marked accumulation of secretory proteins such as procollagen, was always higher than that of the non-dilated ER.
		In the dilated cisternal space, gold particles were freely and evenly distributed, without preferential binding to the luminal surface of the ER membranes.
		The exclusive localization of gold particles in the cisternal space of the ER and nuclear envelopes and the lack of gold particles in the Golgi apparatus, including cis-Golgi cisternae, indicate that PDI is an ER-soluble protein in the chondrocytes and is presumably sorted out in some pre-Golgi compartment and not transported to the Golgi apparatus.

	Endoplasmic reticulum - Wikipedia, the free encyclopedia
		The ER consists of an extensive membrane network of tubes and cisternae (sac-like structures) held together by the cytoskeleton.
		The membrane encloses a space, the cisternal space (or internal lumen) from the cytosol.
		Parts of the ER membrane are continuous with the outer membrane of the nuclear envelope, and the cisternal space of the ER is continuous with the space between the two layers of the nuclear envelope (the intermembrane space).

		Second example of compartmentalization: the endoplasmic reticulum encloses a cisternal space that is separate from the rest of the cytosol by the membranes of the ER.
		The cisternal space is continuous with the intermembrane space of the nuclear envelope (which is why I didn't identify it as a compartment earlier).
		The space in between is the intermembrane space and the inner membrane encloses the inner matrix.

	8.5.3.5
		The membranes enclose a space that is continuous throughout the network and connects with the perinuclear space between the two membranes of the nuclear envelope (Section 8.5.4.1), allowing transport of manufactured substances throughout the cell.
		The fluid occupying the luminal or cisternal space of the ER, which is typically 20-40 nm wide but ranges from 10-70 nm, is called the reticuloplasm.
		Rough ER is an extensive membranous network of flattened sheets with a flattened sac appearance and a continuous cisternal space that communicates directly with the perinuclear space.

	Endoplasmic Reticulum (Site not responding. Last check: 2007-10-30)
		The word endoplasmic means "within" the cytoplasm, and the word reticulum is derived from a word meaning "network." The ER consists of a network of membranous tubules and sacs called cisternae.
		The ER membrane separates its internal compartment, the cisternal space, from the cystosol.
		Because the ER membrane is continuous with the nuclear envelope, the space between the two membranes of the envelope is continuous with the cisternal space of the ER.

	Translocon - Wikipedia, the free encyclopedia
		The translocon (commonly known as a translocator) is the complex of proteins associated with the translocation of nascent polypeptides into the interior (cisternal or luminal) space of the endoplasmic reticulum (ER) from the cytosol.
		Translocators can also move polypeptides (such as damaged proteins targeted for proteasomes) from the cisternal space of the endoplasmic reticulum to the cytosol.
		This requires the expenditure of energy in the form of GTP.

	ER, Golgi, Lysosomes (Site not responding. Last check: 2007-10-30)
		The membranes are called cistera(e) and the space within the ER is the cisternal space (ER lumen) and the remainder of the cytoplasm is the cytosol.
		These proteins are amphiphilic, with their hydrophobic part within the membrane (viz a-helices) and their hydrophilic parts interfacing the cytosol and the intracisternal space of the ER.
		Cisternae are flattened sacs, arranged in parallel fashion and separated by a space of 20-30 nm.

	Early events in the cellular formation of proparathyroid hormone -- Habener et al. 85 (2): 292 -- The Journal of Cell ...
		Approximately 50 percent of pre-prohormone and 25 percent of prohormone were released from the microsomes by their extraction with 1.0 M KCl, whereas 80-90 percent of both was released by treatment with Triton X-100.
		These results in intact cells support the signal hypothesis proposed by Blobel and his co-workers in studies utilizing cell-free systems, inasmuch as the results indicate transfer of prohormone into the cisternal space of the rough endoplasmic reticulum concomitant with the growth of the nascent polypeptide chain.
		Appearance of membrane-sequestered proPTH takes place without entry of pre-proPTH into the cisternal space, suggesting that proteolytic removal of the leader peptide occurs during transfer of the polypeptide through the lipid bilayer.
