Extracting Intact Kidney from Mouse: A Technique to Obtain Kidney Without Renal Capsule from Murine Models

Transcript

Using internal tissue forceps and internal dissection scissors, pinch the intestines and lift them away from the abdominal wall. Simultaneously, cut the underside of the intestines free from the body at the proximal duodenum and distal colon to gain access to the retroperitoneal space containing the kidneys.

Gently pinch and lift the distal end of the ureter with tissue forceps. Using the dissection scissors, cut underneath the pinched ureter towards the kidney until it has become liberated from the surrounding connective tissue. Once the kidneys are exposed, extract them individually.

Fill a silicon elastomer-coated dish with ice-cold KRB solution. Transfer the kidney to the dissection dish and ensure that it is completely submerged. Use fine spring scissors and internal forceps to remove adipose tissue from the base of the kidney to expose the distal renal pelvis or RP and proximal ureter.

Remove the proximal ureter and a portion of the distal RP from the base using fine spring scissors and forceps. Pierce the outer renal capsule with fine-tip forceps, angling the tips away from the kidney body. Using forceps with each hand, pinch the loose ends of the capsule and peel them apart until the remaining renal capsule membrane is removed entirely.
