Area of Science:

Regenerative Medicine
Transplantation Biology
Surgical Innovation

Background:

Autografts of spleen tissue are being explored for potential therapeutic applications.
Understanding optimal preservation methods is crucial for successful spleen tissue transplantation.
Previous studies have not fully elucidated the long-term viability and function of preserved spleen tissue.

Purpose of the Study:

To evaluate the morphology and function of implanted autogenous spleen tissue.
To determine the effects of different preservation methods on spleen tissue viability.
To assess the regenerative capacity and functional recovery of preserved spleen implants.

Main Methods:

Thirty-five male rats underwent various splenectomy and spleen tissue implantation procedures.
Spleen tissue was preserved for 24 hours at room temperature or 4°C in lactated Ringer solution.
Scintigraphic, hematological, and histological analyses were performed after 90 days to assess implant function and regeneration.

Main Results:

Autogenous splenic implants regenerated successfully when preserved at 4°C or immediately after excision.
Scintigraphic studies indicated better phagocytic function in implants preserved at 4°C and immediate implants.
No significant differences in hematological parameters were observed across groups.

Conclusions:

Spleen tissue preserved in lactated Ringer solution at 4°C for 24 hours retains its vitality.
Preserved spleen tissue demonstrates capacity for recovery of hematological and phagocytic functions.
Cold preservation at 4°C is a viable method for maintaining spleen tissue viability for autotransplantation.
