CELL FIBER, CELL FIBER MANUFACTURING SYSTEM, CELL FIBER MANUFACTURING METHOD, AND PROGRAM

This cell fiber production system is provided with: a first flow path through which a first fluid containing cells flows; a second flow path in which a second fluid for preparing a hydrogel flows around the first fluid in the first flow path; and an ejection port that ejects at least the first fluid and the second fluid together. The cell fiber production system is configured so as to feed the first fluid after the second fluid reaches at least the confluence point of the first flow path and the second flow path during the start stage of the production of the cell fiber. 细胞纤维制造系统具有：第1流路，其流通包含细胞的第1流体；第2流路，其使用于调制水凝胶的第2流体合流至第1流路中的第1流体的周围；以及射出口，其至少将第1流体和第2流体一起喷出。细胞纤维制造系统在细胞纤维的制造开始阶段中，以在第2流体至少到达第1流路与第2流路的合流点后，送液第1流体的方式而构成。
