Analysis of Inflammatory Cells in Rat Bladders and the Replacement of Bladder Using Bioprinting Methods

Bladder-related conditions, such as interstitial cystitis/bladder pain syndrome (IC/BPS), are significant medical concerns affecting patient quality of life. IC/BPS patients experience pain, pressure, or discomfort localized in the bladder region. This discomfort often originates from bladder pressure, which can lead to an influx of inflammatory cells, resulting in inflammation, infections, and cystitis. Bladder inflammation may cause pain, increased urinary frequency, and decreased bladder capacity. Addressing these issues necessitates exploring new therapeutic interventions to mitigate bladder inflammation and prevent its recurrence. One emerging solution is the use of 3D bioprinting technology, a process that utilizes 3D printing to fabricate living tissues and organs. Bioprinting has demonstrated potential in various medical applications, including repairing damaged tissues, creating functional replacements, and testing pharmaceutical compounds. We used the bioprinter to create a rat-size bladder and allowed it to culture. We stained and analyzed hundreds of rat bladders to further monitor the effects of surgical implantation of inflammation detectors. Further studies will allow us to see the effect of the 3D printed bladder in the rat.
