The procedure involves the use of fine needles or micropipettes to inject the substance into the tissue. The process can be guided by imaging techniques such as ultrasound or microscopy to ensure accuracy. The steps generally include:
1. Preparation: Selecting the right needle or micropipette and the substance to be injected. 2. Anesthesia: Administering local or general anesthesia to minimize pain and discomfort. 3. Injection: Carefully inserting the needle into the target tissue and delivering the substance. 4. Observation: Monitoring the effects using various histological techniques like staining and imaging.
