Micropropagation is just cloning in a sterile environment on a nutrient rich jello, and a dash of rooting hormones. You can take those tiny branches too small for normal cloning, rinse em in diluted bleach water, cut off the now damaged tips, and put the explant in the jello with parafilm on top.
Tissue culture is the same idea, but you can start with a leaf or a stem or whatever cells you have on hand. First step is to first grow a callus, then you can step by step force it to grow each new organ that it's missing from that callus.
2019 is going to have a major influx of micropropagation.
