Preserving post mortem human tissues for histology is challenging. A novel rehydration solution and microwave stimulation enable successful histological and immunohistochemical analysis of room-temperature stored samples.

Area of Science:

  • Forensic Pathology
  • Histology
  • Biochemistry

Context:

  • Post mortem tissue samples from human organs (skin, muscle, liver, kidney, brain) were stored at room temperature for one year.
  • Standard histological preparation and identification became impossible after a few hours without pretreatment.

Purpose:

  • To develop a method for preserving and analyzing post mortem human tissue samples stored at room temperature.
  • To enable histological and immunohistochemical examinations of aged tissue samples.

Summary:

  • A rehydration solution (30 ml absolute ethanol, 50 ml aqua dest., 20 ml 0.2 M phosphate buffer pH 7.0) successfully reconstituted and enabled identification of aged tissue samples.
  • Immunohistochemical examinations remained unaffected by the rehydration solution.

  • Microwave stimulation reduced the rehydration process time from 24 hours to 4 hours.

    • Impact:

    • This method significantly extends the viability of post mortem tissue samples for diagnostic and research purposes.
    • Facilitates reliable histological and immunohistochemical analysis of tissues stored under suboptimal conditions.
    • Improves efficiency in forensic and medical investigations involving tissue analysis.
