Cell Stem Cell 22(5):653-667.e5. doi: 10.1016/j.stem.2018.03.017 PMID: 29656941

Objective: To investigate whether a lineage relationship exists between two stem cell compartments that contribute to airway repair – basal cells in the surface airway epithelium (SAE) and an unknown submucosal gland (SMG) celltype.

Summary: Using lineage tracing of glandular myoepithelial cells (MECs), they demonstrate that MECs can give rise to seven cell types of the SAE and SMGs following severe airway injury. MECs progressively adopted a basal cell phenotype on the SAE and established asting progenitors capable of further regeneration following reinjury. MECs activate Wnt-regulated transcription factors (Lef-1/TCF7) following injury and Lef-1 induction in cultured MECs promoted transition to a basal cell phenotype. Surprisingly, dose-dependent MEC conditional activation of Lef-1in vivo promoted self-limited airway regeneration in the absence of injury.

Objective: To quantify the effects of chronic intermittent hypoxia (CIH) on AT1R- and AT2R-like immunoreactivity in the rostroventrolateral medulla (RVLM) and paraventricular nucleus of the hypothalamus (PVN), central regions that are important components of the extended chemoreflex pathway.

Summary: Exposure to CIH of at least 5 days duration augmented AT1R-like immunoreactivity in RVLM. In contrast, CIH exposure did not affect AT2R-like reactivity in RVLM or that of either Ang II receptor subtype in PVN.

Usage: Immunoreactivity, immunostaining. For immunoreactivity assays, antibodies were diluted in the blocking solution with 0.05% sodium azide at the following concentrations: AT-1R, (1:1600) and AT-2R, (1:5000).

Objective: To determine roles of cryptochromes (CRY) in the retinal clock.

Objective: The clustered protocadherins (Pcdhs) comprise 58 cadherin-related proteins encoded by three tandemly arrayed gene clusters, Pcdh- , Pcdh- , and Pcdh- (Pcdha, Pcdhb, and Pcdhg, respectively). This study sought to determine roles of Pcdhas and Pcdhgs in the retina and cerebellum from mice (both sexes) lacking one or both clusters.

Summary: Study examined two regions of the CNS, the retina and cerebellum and showed that the 14 -Pcdhs and 22 -Pcdhs act synergistically to mediate neuronal survival and dendrite patterning. In retina, Pcdhgs are essential for survival of inner retinal neurons and dendritic self-avoidance of starburst amacrine cells, whereas Pcdhas are dispensable for both processes.

Usage: Anti-Melanopsin (1:5000) used to quantify two mutually exclusive RGC cell types, the Brn3a RGCs and the melanopsin-positive intrinsically photo- sensitive RGCs (Mel ipRGCs).
