Most people meet plant cell culture in the grocery store without knowing it. You see it in the perfect row of blueberries, the identical bananas, the white orchids that look the same every single year. You do not see the lab bench and the flask behind them.

On The Innovators, I talked with Yoni Kalin, CEO of Plant Cell Technology, about the quiet infrastructure under all of that. His company has been working in plant tissue culture since 1993. What started as a small family business selling “pet plants” in jars has grown into a Utah based factory, a catalog of more than 500 products, and a bridge between plants, animal cells, fungi, and the people who work with them.

At the core, Plant Cell Technology makes the media and tools that keep cells alive and dividing. In the plant world that means the gel or liquid that feeds tiny cuttings, the nutrients that turn one node into a full clone. In the animal world that means the formulas that keep mammalian cells healthy in dishes and flasks. You can think of them as the food and basic kit that every lab needs before any vaccine or seedling can exist.

For the first thirty years they stayed in the plant lane. Last year they bought a manufacturing facility and stepped into mammalian cell culture. Now they blend media for human, animal, and insect cells as well. That move puts them inside the engine room of pharma and biotech, where the same cell lines are used for decades to test drugs and make biologic medicines.

Yoni gave a simple example. CHO cells, Chinese hamster ovary cells, have been in use since the middle of the last century. The original cells came from one animal. That line has been split and expanded for more than eighty years. Those cells are a standard test bed. If you want to grow a protein drug or check how something behaves, you feed those cells and watch. That kind of work used to mean a lot of live animal testing. The more you can do in culture, the less you have to do in a whole animal.

Plant cell culture is less visible but just as important. Instead of planting a seed and accepting whatever mix of traits comes back, growers take a cutting from a known plant, usually a meristem or small node, and regrow it in sterile media. The result is an exact clone of the parent. Every plant you make that way has the same genetics and the same performance.

If you are a berry grower, that consistency matters. It is the reason the box of blueberries you pick up in January tastes like the one you bought in July. If you are a greenhouse operator selling fancy houseplants, it means you can produce a thousand copies of the one pink variegated plant everyone wants instead of hoping more seeds turn out the same way. In orchards, forests, and replanting projects, it means you can fill a hillside with trees that all have the traits you need for that climate.

It is also the reason you can walk into a store like Trader Joe’s or Home Depot and see the same orchid color and shape every year. Orchid seeds are rough to work with. Cloning them in tissue culture lets growers keep exact copies of the best lines in circulation.

Plant Cell Technology sits in that supply chain as a “picks and shovels” vendor, to borrow Yoni’s phrase. They do not sell the fruit or the orchids. They sell the media, the bioreactors, the lab gear, and the training that lets growers and researchers do the work.

That education piece is important and it is where things get interesting outside the pure lab. Until a few years ago, if you wanted to learn plant tissue culture, you went to a university or a big corporate lab. You paid tuition or you got hired. Everyone else was on the outside.

Around 2020, while people were learning to bake sourdough and dance on short videos, Plant Cell Technology started posting long form instructional content. They now have hundreds of free videos that cover the basics,
