We collected 10 μm-thick cryosections in accordance with standard procedure for Immunohistochemistry and EdU staining. When combined with EdU detection, we carried out firstly EdU staining using Click-iT EdU kit (Invitrogen, C10340) in accordance with the manufacturer’s instructions, then followed by a standard immunohistochemistry protocol as previously described (Fei et al., 2017 (link)). In brief, after PBS wash and permeabilization with PBST, slides were blocked in 5% serum prepared in PBST, then incubated with primary antibodies overnight at 4°C, followed by sequential PBST washes and secondary antibody (with DAPI, Sigma-Aldrich, D9542) incubation, and finally mounted using Mowiol 4-88 (Sigma-Aldrich, 9002-89-5) mounting medium after several PBST washes. Fluorescence images were acquired with an Olympus IX83 microscope (Olympus, Tokyo, Japan), using ×20 objectives and analyzed using FIJI. The following antibodies were used in this study, MBP (Genetex, GTX761141), PRRX1 (Gerber et al., 2018 (link)), βIII-TUBULIN (R&D, MAB1195), SOX9 (Chemicon, Ab5535), PAX7 (DSHB, AB528428), MEF2C (Santa Cruz, sc-365862), phospho-Histone H3 (Abcam, 10543), MHC (DSHB, A4.1025). Alexa 488-donkey-anti-mouse IgG (Jackson, 711-547-003), Alexa 555-donkey-anti-rat IgG (Invitrogen, SA5-10027), Alexa 647-donkey-anti-mouse IgG (Jackson, 715-607-003), CY3-donkey-anti-mouse IgG (Jackson, 715-165-151).

For immunohistochemistry, fixed coverslips were incubated in blocking solution (3% normal donkey serum, 0.3% Triton X-100 in TBS) at room temperature for 1 hour. Primary antibodies, mouse anti-nestin (1:500, Abcam), guinea pig anti-synapsin1/2 (1:500; Synaptic Systems), rabbit anti-RFP (1:500; Rockland), or chicken anti-neurofilament (M+H; 1:1000; Aves Labs) were diluted in antibody diluent solution (1% normal donkey serum in 0.3% Triton X-100 in TBS) and incubated overnight at 4°C. Samples were then rinsed three times in TBS and incubated in secondary antibody solution (Alexa 488 donkey anti-chicken IgG; Alexa 594 donkey anti-rabbit IgG, Alexa 647 donkey anti-mouse IgG, and Alexa 405 donkey anti-guinea pig IgG all used at 1:500 (Jackson Immuno Research)) in antibody diluent solution at 4°C overnight. Coverslips were rinsed three times in TBS and mounted with ProLong Gold Mounting medium (Life Technologies). Images were collected using a 63x oil-immersion objective on a Zeiss LSM800 confocal microscope and processed with airyscan. Coverslips were used to quantify colocalization as described below.

Cells from three-dimensional cultures were fixed with 2% paraformaldehyde/PBS for 10 min, permeabilized in 0.5% Triton X-100/10% Goat serum/10% fish gelatin/PBS for 1 h and incubated overnight in primary antibodies. The primary antibodies were used at the following dilutions: Par6B 1/200 (Santa Cruz #sc-67393), aPKCι 1/100 (BD Transduction #610175), Par3 1/200 (Millipore #07-330), CD13 1/100 (Abcam #ab108382), CD13 1/50 (Sigma #HPA004625), E-cadherin 1/200 (Cell Signaling #3195 S), ZO-1 1/100 (Cell Signaling #8193), Ezrin 1/200 (Cell Signaling #3145), Pals1 1/100 (proteintech group #17710-1-AP), β1-integrin 1/200 (Abcam #ab30394), V5 1/200 (Thermo Fisher Scientific # R960-25), laminin 1/200 (Abcam #ab11575), α-Tubulin 1/200 (Sigma #T9026), Phalloidin 1/100 (Invitrogen #A34055), and endoplasmic reticulum (ER) marker-Calreticulin 1/200 (Abcam #ab92516). The secondary antibodies conjugated to Alexa488-Donkey anti-Rabbit IgG (Jackson ImmunoResearch Laboratories #711-545-152), Goat Anti-Mouse IgG (Cy3) (Jackson ImmunoResearch Laboratories #115-165-166) and Alexa647-Donkey Anti-Mouse IgG (Jackson ImmunoResearch Laboratories #715-605-151) were used at 1:750. DNA was detected with Hoechst dye 33258. Confocal imaging was performed using LSM700 from Zeiss with 20×/0.8NA or 40×/1.4NA objective lenses and processed using FIJI/ImageJ software.

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.
