PG - 1220-4 AB - We describe here a simple and versatile method of fluorescence in situ hybridization (FISH) on paraffin-embedded tissue sections with specific application in the study of microchimerism, that is, the presence of intact foreign cells within an individual. This is accomplished through the use of X and Y chromosome-specific probes to identify the presence of male nuclei within a tissue section from a female, and vice versa. This technique requires only minor modification if at first the hybridization does not yield fluorescent signals of high quality. Analysis of a wide variety of tissue types is possible with this method, and multiple tissue types from one or more individuals can be processed in the same hybridization reaction. This robust FISH method has been used successfully in our laboratory to investigate fetal cell microchimerism in the following paraffin-embedded tissue types: skin, lung, thyroid, adrenal gland, lymph node, heart, spleen, liver, pancreas, kidney, and intestine.
