acid) polysaccharides onto the surface of normal and cancer
human cells was studied with the use of dynamic light
scattering. A method for preparation of multilayer polymeric
shell by means of electrostatic adsorption of polysaccharides
onto cell plasma membrane has been proposed. According to
confocal microscopy, the polymeric shell evenly covers the cell
and is 1-5 μm in thickness. Under experimental conditions,
the modification with polysaccharides inhibits human skin
fibroblasts growth but does not exhibit cytotoxicity to
HeLa cells. We developed an approach to controllable and
reversible aggregation of modified cells by their cross-linking
in the presence of calcium ion. Resulting aggregates have
spherical shape and the size of 100-500 μm. Proposed
approaches and methods represent an alternative to cell
microencapsulation technique and are of interest for the
development of three-dimensional cell models and their
delivery in vivo.</p></abstract><trans-abstract xml:lang="ru"><p>Методом динамического рассеяния света исследованы
процессы осаждения катионного (хитозана) и анионного
(альгиновой кислоты) полисахаридов на поверхности нормальных и опухолевых клеток человека. Предложен способ
формирования многослойной полимерной оболочки, образуемой путем электростатической адсорбции полисахаридов на поверхности плазмалеммы клеток. По данным конфокальной микроскопии полимерная оболочка равномерно
покрывает клетки и имеет толщину в 1-5 мкм. В условиях
эксперимента модификация полисахаридами угнетает жизнеспособность фибробластов кожи человека, но не проявляет цитотоксичности для клеток HeLa. Предложен подход к
контролируемой и обратимой агрегации модифицированных
клеток путем их кросс-сшивки ионами кальция. Образующиеся при этом многоклеточные агрегаты имеют сферическую форму и размер от 100 до 500 мкм. Предложенные
подходы и методы являются альтернативой микроинкапсуляции клеток и представляют интерес для создания трехмерных моделей клеток и технологий их доставки in vivo.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cell microencapsulation</kwd><kwd>polysaccharides</kwd><kwd>plasma membrane</kwd><kwd>cell spheroids</kwd><kwd>tissue engineering</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>микроинкапсуляция клеток</kwd><kwd>полисахариды</kwd><kwd>плазматическая мембрана</kwd><kwd>клеточные сфероиды</kwd><kwd>тканевая инженерия</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Barry F.P., Murphy J.M.
