Roberto Eusebio Mancini

Roberto Eusebio Mancini Doria, Argentine morphologist (Buenos Aires 26 September 1914 – 03 February 1977)

Son of Italian immigrants



Internationally recognized as one of world’s foremost experts on histophysiology of human testis 


Performed studies about testes functions, connective tissue in human and animals and use of fluorescent substances 


Characterized cytological, embryological and histochemically the child human testis

With R. Narvaitz & J.C. Lavieri. Origin and development of the germinative epithelium and Sertoli cells in the human testis. Cytological, cytochemical and quantitative study. Anat. Rec. 136:477-89, 1960

With O. Vilar, I.E. Lavieri, I.A. Andrade & I.I. Heinrich. Development of Leydig cells in the normal human testis. Am. J. Anat. 112:203-14, 1963


Characterized the cytology of cryptorchid testis

With E. Rosemberg, M. Cullen, J.C. Lavieri, O. Vilar, C. Bergada & J.A. Andrada. Cryptorchid and scrotal human testis. I. Cytological, cytochemical and quantitative studies. Clin. Endocr. 25:911, 1965


Proposed the role of connective tissue as a transient depot for the extravascular pool of serum proteins 


With L. Lustig & B. Denduchis authored the first report on the chemical properties of the basement membrane of the seminiferous tubular wall (1975) and demonstrated a partial immunological identity among basement membranes of distinct species (1977)

 

METHODS/TECHNIQUES

With E. Sacerdote de Lustig introduced modifications to techniques for measuring the presence of glycogen in embryonary tissues  (1941-2)
