Quantitative Analysis of pMLC2 Localization

Images from fixed tissues were acquired using an LSM 700 microscope (Zeiss) equipped with a ×63/1.4 Plan Apochromat DIC oil immersion objective. Quantifications of pMLC2 fluorescence intensities at the back, the front, and the side of the cluster were performed as previously described6 (link).
For more precise analysis of pMLC2 localization and for the line scan analysis, we acquired images from fixed tissues with the Airyscan detector of a Zeiss LSM880 confocal equipped with a ×63/1.4 Plan Apochromat oil immersion objective. Line scans were performed on the Zen Blue software and plotted in GraphPad Prism. Specific line scan were chosen according to the base of the protrusion. The protrusion bases were determined manually by its neck shape (opposite negative curvature shapes). The signal were normalized to the maximal signal of pSqh intensity.

Embryonic Cartilage Development Imaging

E17.5 embryos were decalcified in 20% EDTA at 4°C for 3 days, while E12.5 and E13.5 embryos did not require decalcification. Embryos were fixed in 4% paraformaldehyde (PFA) for 48 hours and embedded in paraffin for sectioning in the sagittal plane. 7μm sections were stained with 1% Safranin-O, 0.05% Fast Green, and 1% Hematoxylin, and then visualized by light microscopy (Axio Imager 2, Carl Zeiss) using 20×/0,5 EC Plan-Neofluar (Carl Zeiss) or 63×/1,4 Plan-Apochromat (Carl Zeiss) objectives. Imaging of sections was conducted with the Axiocam 105 color camera (Carl Zeiss) using Zen2™ software (Carl Zeiss). Morphological analysis was performed on eight E12.5, two E13.5, and ten E17.5 null and wild-type embryos. Aspect ratio was measured using ImageJ 1.52a (http://rsb.info.nih.gov/ij/), where the major axis was divided by the minor axis determined by Fit Ellipse measurements. Aspect ratio data were collected from five E17.5 embryos per genotype with three discs per embryo (15 discs).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
