The left kidney was used for glomerular injury analysis in H&E stained (Sigma) sections of the kidney (5 μm) embedded in Paraplast. Digital images from thirty glomeruli per animal were obtained using a light microscope (Leica) at 400x magnification. After digitalization, Bowman's capsule area (BCA), glomerular tuft area (GTA), and Bowman's space area (BSA) were traced and calculated using a computerized morphometric analysis system (Image Pro-Plus 4.1; Media Cybernetics, Silver Spring, MD, USA).
Lipid content was measured using quantitative histochemistry of Oil Red O (Sigma-Aldrich) stained kidneys. Tissue sections (8 μm thickness) obtained in a cryostat were examined by light microscopy at 200x magnification and analyzed by a computerized morphometric analysis system (Image Pro-Plus 4.1; Media Cybernetics, Silver Spring, MD, USA). The slides were counterstained with hematoxylin to visualize the nuclei. Lipid accumulation was determined in 12 images per animal based on the percentage of area occupied by lipid droplets. Histological analyses were blinded conducted by RO Pereira.

Microvessel Density Quantification Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
The tumor MVD was calculated by the method presented by Weidner with certain modifications (25 (link)). First, five fields with the highest blood vessels densities were identified at ×100 magnification under a light microscope; microvessels were then counted on the monitor of a computer image analysis system (Image Pro Plus 4; Media Cybernetics, Rockville, MD, USA) under a light microscope at ×200 magnification, and the mean microvessel number was calculated as the MVD value. No matter whether a tube was formed, any single EC or multiple ECs arranged compactly were assumed to be a blood vessel. When a tubular structure was not continuous phase, its branches were also viewed as a blood vessels. Cells that were difficult to distinguish or dimly stained, as well as thick-walled muscular vessels or lumen of >50 µm (equivalent to ≥1 cm at magnification, ×200) were not counted.

All confocal images (except FRET, which is described below) were acquired with a microscope (TCS SP5; Leica) equipped with the software LAS AF 1.82 and following lasers: optically pumped semiconductor laser 488 nm/270 mW, diode-pumped solid-state laser 561 nm/20 mW, and HeNe 633 nm/12 mW. For fixed samples, the glycerol immersion objective HCX Plan Apochromat 63×/1.3 NA GLYC CORR CS (glycerol correction; Leica) at RT was used. Live cell microscopy (FRAP and Motility analysis, see below) was carried with HCX Apochromat L 63×/0.90 NA water immersion objective. Neurons were maintained at 37°C and 5% CO2 in a custom chamber (The Box; Life Imaging Services) in Neurobasal medium containing B27 supplement and 0.5 mM l-glutamine throughout the imaging session.
For quantification of phospho-cofilin in Fig. 2 b, fluorescent wide-field images were acquired with microscope (AxioImager.M1; Carl Zeiss) equipped with camera (AxioCam HR; Carl Zeiss) and AxioVision 4 software (Carl Zeiss). The hippocampal neurons were imaged with 40× objective EC Plan Neofluar/0.75/Ph2 at RT. The light-emitting diode system (Colibri; Carl Zeiss) with 470- and 555-nm modules was used, and the beam combiners were BC490, BC425 (for GFP), and BC565 (for Alexa Flour 568).

Quantifying Actin Dynamics in TSPC Subtypes

Check if the same lab product or an alternative is used in the 5 most similar protocols
Quantification of Y- and A-TSPC (EphA4-Fc, EphB2-Fc, and Fc-control) cell area was obtained from F-actin images by measuring 50 cells from each donor with the polygonal tool of the ImageProPlus4 software (Media Cybernetics). Actin dynamics of Y- and A-TSPC (EphA4-Fc, EphB2-Fc, and Fc-control) was analyzed by latrunculin A experiment, carried out as described in (Kohler et al., 2013 (link)). latrunculin A inhibits actin polymerization by sequestering monomeric G-actin and thereby disrupts the turnover of actin filaments. In brief, the four different TSPC groups, Y- and A-TSPC with EphA4-Fc, EphB2-Fc, and Fc-control, (5.5 × 103 cells/cm2) were grown in 96 well plates and pre-cultured for 48 h. Then, cells were treated with 0.4 μM latrunculin A (Sigma–Aldrich), fixed at different time intervals (0, 2, 5, 8, 10, 20, 30, and 60 min), stained with 0.6 μM phalloidin-546 (Thermo Scientific) and fluorescence signals were recorded at 573 nm using a SAFIRE2 microplate reader (Tecan, Germany). In each group, F-actin content at time point 0 was set to 100%. latrunculin A analyses were reproduced three independent times for all Y- and A-TSPC donors in triplicates (n = 9).

The rats were fixed on a laboratory-made operating table after anesthesia. The affected limb was held firm with one tack in front of and one behind the elbow joint of the affected limb. An incision of the skin was made in the middle of the upper left arm of the rat to expose and then bluntly separate the nerve. In the sham operation group and epineurial neurorrhaphy group, the median nerves were directly stimulated. In the musculocutaneous nerve transposition, medial pectoral nerve transposition, and radial nerve muscular branch transposition groups, a site 5 mm from the sleeve suture was stimulated with a Synergy electrophysiologic apparatus (Medelec Synergy; Oxford Instrument Inc., United Kingdom) with 0.9 mA continuous square waves at 50 Hz. The position of each left front paw was recorded with a digital camera (Sony, Tokyo, Japan) before and after stimulation. Results were synthesized with Image Pro Plus 4.5 software (Media Cybernetics, Silver Spring, MD, USA), and the angle of wrist flexion was measured.
