请用更地道、更科学、更书面化的英语表达如下内容：For HEO complex a total of 100 EEOs 5 × 104 ESCs and 15 × 104 HUVECs were used for every 30 μl of hydrogel For EO complex 100 EEOs and 20 × 104 ESCs were used for every 30 μl o

In the case of the HEO complex, a volume of 30 μl of hydrogel required the utilization of a total of 100 endothelialized embryoid bodies (EEOs), 5 × 104 embryonic stem cells (ESCs), and 15 × 104 human umbilical vein endothelial cells (HUVECs). Conversely, for the EO complex, a volume of 30 μl of hydrogel necessitated the inclusion of 100 EEOs and 20 × 104 ESCs.
