Analysis of axonal regeneration following SCI.

Adult 8-week-old cre+Pfn1 mice and 15-week-old female C57BL/6 mice were deeply anesthetized with isoflurane. Laminectomy was performed at the thoracic T8 to T9 level and the spinal cord was cut using a micro feather ophthalmic scalpel (Feather, Safety Razor Co). For CL experiments, animals were subjected to a sciatic nerve transection 1 week prior to SCI. In cre+Pfn1 mice, analysis of dorsal column axon regeneration after either SCI or CL was performed 4 weeks after injury. Dorsal column axons were traced by injecting 2 μL of 1% CT-B (List Biologicals, 103B) with a 10-μL syringe (Hamilton) into the left sciatic nerve 4 days prior to euthanasia (day 24 after injury). On day 28, mice were perfused with 4% PFA and the spinal cords were postfixed for 1 week at 4°C and later cryoprotected in 30% sucrose. Serial tissue sagittal cryosections (50 μm thickness) were collected for free-floating immunohistochemistry. Sections were incubated overnight at 4°C with goat anti–CT-B primary antibody (1:30,000; List Biologicals, 703).

EAE induction and clinical evaluation

EAE was induced in 8-week-old female C57BL/6 mice by subcutaneous administration of 250 μg MOG35–55 peptide (synthesized by Sigma Laboratories, Israel) into the left paralumbar region. The MOG35–55 peptide had been emulsified in complete Freund’s adjuvant (CFA) containing 5 mg/ml heat-killed Mycobacterium tuberculosis. Immediately after this injection and at 48 h after the injection, the mice were intraperitoneally administered 200 ng of the pertussis toxin (List Biological Industries, San Diego CA, USA). All the animals were examined daily and evaluated for clinical signs of disease. …

Tissues and cells

… MDA-MB-246, MDA-MB-231, T47D and ZR-75-30 cells were used as model BCa lines (Chinese Cell Bank). Cells were cultured in DMEM plus 10% FBS and 1% (v/v) pen/strep at 37 °C in a 5% CO2 humidified atmosphere. The normal epithelial breast cell line MCF-10A was cultured in MEBM basal medium (Lonza, Basel, Switzerland) supplemented with the MEGM Single Quot Kit (Lonza) and cholera toxin (List Biological Labs, Campbell, CA).
