In this case, an assessment of engraftment requires a detailed morphological characterization, in particular an analysis of the neuronal and glial populations. In the experiment performed, human iPSC-derived neural progenitors transplanted into a rat striatum produced a mixed neuron and astrocyte population <italic>in vivo </italic>by the sixth month after transplantation. The morphological characteristics and neurochemical profile of the xenografted astrocytes were similar to those of mature human astroglia. Unlike neurons, astrocytes migrated to the surrounding structures and the density and pattern of their distribution in the striatum and cerebral cortex differed, which indicates that the microenvironment affects human glia integration. The graft was characterized by the zonal features of glial cell morphology, which was a reflection of cell maturation in the central area, glial shaft formation around the transplanted neurons, and migration to the surrounding structures.</p></abstract><trans-abstract xml:lang="ru"><p>Трансплантация смешанной астроцитарной и нейрональной культуры представляет интерес для разработки методов клеточной терапии нейродегенеративных заболеваний. Вместе с тем, для оценки развития трансплантата необходима подробная морфологическая характеристика, включающая анализ нейрональных и глиальных популяций. В проведенном эксперименте трансплантированные нейрональные предшественники, полученные из ИПСК человека, к шестому месяцу после трансплантации в стриатум крысы давали <italic>in vivo</italic> смешанную популяцию нейронов и астроцитов. Ксенотрансплантированные астроциты по морфологическим характеристикам и нейрохимическому профилю были сходны с зрелой астроглией человека. В отличие от нейронов, астроциты мигрировали в окружающие структуры, причем плотность и характер их распределения в стриатуме и коре головного мозга различались, что свидетельствует о влиянии микроокружения на интеграцию глии человека. В трансплантате выявляли зональные особенности морфологии глиальных клеток, отражающие их созревание в центральной зоне, формирование глиального вала вокруг трансплантированных нейронов и миграцию в окружающие структуры.</p></trans-abstract><kwd-group xml:lang="en"><kwd>iPSC</kwd><kwd>neural precursors</kwd><kwd>transplantation</kwd><kwd>striatum</kwd><kwd>astrocytes</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ИПСК</kwd><kwd>нейрональные предшественники</kwd><kwd>трансплантация</kwd><kwd>стриатум</kwd><kwd>астроциты</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Doss M.X., Sachinidis A. // Cells. 2019.
