Gliech, Holland Labs, John Hopkins School of Medicine, Baltimore, US. The Holland lab is interested in the molecular mechanisms that control accurate chromosome distribution and the role that mitotic errors play in human health and disease.

NAVIGATOR tile scan (3x2) of a whole mount of mouse diaphragm muscle
Blue: Nuclei, B&W: F-actin, Red: Nicotinic acetylcholine receptors, a principal postsynaptic component of neuromuscular junctions. Green: Tyrosine hydroxylase, a marker for sympathetic neurons. The video shows the spatial relationship between muscle fibers, sympathetic neurons, and neuromuscular junctions. Processes of sympathetic neurons partially run orthogonally to muscle fibers and in parallel to each other (lower part) or they line up with the long axis of muscle fibers and make contact with neuromuscular junctions (upper parts). LIGHTNING automatically reveals the finest details applying an adaptive process for extraction of hidden information in the image.

Whole mount mouse diaphragm muscle was stained for nicotinic acetylcholine receptors, a principal postsynaptic component of neuromuscular junctions (red) and tyrosine hydroxylase, a marker for sympathetic neurones (green). The image shows a direct comparison between 3D-projections of a group of neuromuscular junctions with (right) or without (left) deconvolution using Lightning software. Upon deconvolution, a clearly enhanced definition of sympathetic neuronal processes and of the fine patterned structure of the postsynaptic distribution of acetylcholine receptors becomes evident. Note the close spatial vicinity between sympathetic neurones and neuromuscular junctions. Courtesy of Tatjana Straka and Rüdiger Rudolf, University of Applied Science, Mannheim.
