Summary of estimated volumetric growth by stage
| Stage | Parent radius (μm) |
Offspring radius (μm) |
Somatic cell radius (μm) |
Parental ECM volume change (est., mm3) |
Parental ECM growth rate (est., mm3/h) |
|---|---|---|---|---|---|
| I | 106±6 | 16±2 | 2.8±0.5 | ↓ | ↓ |
| II | 221±19 | 29±2 | 3.9±0.4 | 0.039 | 0.0026 |
| III | 244±13 | 30±4 | 4.0±0.3 | 0.015 | 0.0025 |
| IV | 422±6 | 79±6 | 4.2±0.4 | 0.229 | 0.0143 |
| S | 265±26 | 15±1 | 4.1±0.3 | n/a | n/a |
Values reported are mean SD. Estimated ECM volume is volume of spheroid minus that estimated of juveniles and somatic cells, as explained in SI Appendix, Table S1. Values in final two columns represent changes with respect to preceding stage.
