Autologous Blood-Induced Intracerebral Hemorrhage (ICH) Model

Creative Bioarray has established a stable intracerebral hemorrhage (ICH) model induced by autologous blood. We provide services including in vivo and in vitro testing for clients worldwide to facilitate your brilliant studies. According to your specific needs, our scientists will work with you to assist you from initial study design to final reporting and analysis of your data to provide you with reliable, reproducible results at the most favorable prices.

ICH is an extremely serious form of stroke that is impossible to treat It mostly occurs in the basal ganglia, a white matter-rich area that is especially vulnerable to mechanical stress in response to hemorrhage, resulting in hemiplegia, partial sensory impairment, ectopic blindness, and other complications. The intracerebral injection of the autologous blood model is a simple and effective technique for the production of brain parenchymal hematoma.

Our Autologous Blood-Induced Intracerebral Hemorrhage (ICH) Model

  • Available Animal

Rat

  • Modeling Method

Animals are immobilized in a prone position on a stereotaxic apparatus. After amputating the tail tip, blood is extracted from the resulting wound. Next, a precise hole is drilled through the right parietal bone. Carefully, a micro-syringe is inserted to a depth of 5.5 mm, targeting the right striatum. Finally, the autologous blood is gradually infused to induce the cerebral hemorrhage model. Animals in the sham group are subjected to the same procedures as the ICH mice, but no blood is injected.

  • Endpoints
  • Clinical score: Longa score, Bederson score
  • Survival rate
  • Histology analysis: H&E staining, TUNEL staining, IHC
  • Cytokine analysis
  • Brain water content
  • qPCR or Western blot
  • Other customized endpoints

Example Data

Rat models of intracerebral hemorrhage (ICH) showing Zea Longa scores and hematoma formation: (A–C) Rats with scores 1, 2, and 3; (D) brain after autologous blood infusion; (E) ICH-induced hematoma; (F) sham operation without hematoma.Fig. 1 Scoring of intracerebral hemorrhage model and hematoma formation. (A–C) Rats with Zea Longa scores of 1, 2, and 3, respectively; (D) gross brain specimen after autologous blood infusion; (E) hematoma following ICH; and (F) no hematoma in the sham-operated rats. (Li et al. 2020)

H and E stained images of brain tissue at 40x magnification showing hematoma formation in intracerebral hemorrhage (ICH) models: (A) Normal, (B) sham operation with normal tissue, (C–J) ICH and ICH/HF groups with visible hematomas.Fig. 2 H&E staining showing hematoma formation (×40). (A) Normal and (B) sham-operated groups had normal brain tissue in the basal ganglia; (C–J) ICH and ICH/HF groups had hematomas at each time point. (Li et al. 2020)
