Ph computer software. The Tom20stained area was divided by the TH-stained region to figure out the total mitochondrial content in DNs for each and every case. To evaluate mitochondrial distributions in neurites, the amount of neurites in at the very least a single Tom20-stained area and total neurites have been manually counted for 30 randomly selected cells in the fluorescence photos of every single control- and patient-derived case. Thereafter, the amount of neurites in at the very least one Tom20-stained region was divided by the total quantity of neurites to identify the proportion of mitochondria-containing neurites.ordinarily developing boys were calculated with the results of a normally developing boy (Ctrl-SHED1 and Ctrl-DN1) set as 1.|RESULTS3.1 | Impaired neurite development and altered DN marker expression in patientderived DNs (DS-DNs)Fluorescent in situ hybridization analysis showed 3 copies of HSA21 in SHEDs obtained from 3 men and women with DS (Figure S1). Much more than 99 SHEDs in each groups expressed mesenchymal stem cell markers (CD44, CD73, and CD90) at comparable levels, and 1 SHEDs expressed CD34 and CD45 (hematopoietic markers) (Figure S2), as demonstrated by a previous study on SHED characterization.34 SHEDs in the control and patient groups showed comparable fibroblast-like morphologies, along with the frequencies of colony-forming cells have been comparable among the two groups (Figure S3). The SHEDs in each groups were differentiated into DNs (Figure 1A);two.|Statistical analysesStatistical analyses had been performed using Student’s t-tests with Prism9 (GraphPad).
