Background:

Obtaining optimal cytogenetic results from post-mortem tissues presents significant challenges for researchers.
Degraded tissues, such as macerated or necrosed samples, often yield inadequate chromosomal data.
Identifying a reliable biological tissue source for cytogenetic analysis in deceased individuals is crucial.

Purpose of the Study:

To introduce and validate a novel method for preparing post-mortem biological tissues for chromosomal studies.
To evaluate the efficacy of enzymatic digestion of cartilage for cytogenetic analysis in human fetuses and infants.
To establish human cartilage as a preferred tissue source for cytogenetic investigations in stillborn fetuses and deceased infants.

Main Methods:

The study involved enzymatic digestion of cartilage tissue obtained from human fetuses and infants.
The processed cartilage was then subjected to standard cytogenetic analysis.
The method was implemented and assessed within a laboratory setting.

Main Results:

The described method, involving enzymatic digestion of cartilage, consistently yielded acceptable cytogenetic results.
Human cartilage proved to be a viable and effective post-mortem tissue source for chromosomal studies.
The technique demonstrated success in a laboratory environment.

Conclusions:

Human cartilage is a highly suitable biological tissue for cytogenetic studies in post-mortem cases, particularly in fetuses and infants.
The enzymatic digestion method enhances the quality of chromosomal preparations from challenging post-mortem samples.
This approach offers a reliable solution for cytogenetic analysis when dealing with deceased individuals.
