Scientists already know how to turn adult cells into stem cells, and-in mice-how to coax those into eggs and sperm. “We are one step closer now to making sperm in a dish,” says Sasaki. Most recently, the team managed to get what are known as spermatogonia-the immediate precursor of sperm cells. Since then, the team has been trying to encourage these primitive cells to mature into sperm in the lab. “It’s kind of a recipe to make an early-stage cell,” says Sasaki. Meanwhile, in 2015, Kotaro Sasaki, a former mentee of Saitou based at the University of Pennsylvania, turned men’s blood cells into stem cells and generated the primordial cells that lead to sperm. His team has pushed human cells to the oogonia stage-the stage before they become eggs-after culturing cells in the lab for four months. Researchers have managed to generate immature sex cells and are working on ways to push the cells further along, to a state where they can be used to create an embryo. The race is now on to do the same with human cells.

The trick is working out how to encourage the stem cells to form egg or sperm cells. Much of the work relies on a Nobel Prize–winning technique developed in 2006 that allows scientists to turn adult cells into stem cells, which can form pretty much any specialized cell in the body: heart cell, liver cell, brain cell-you name it. Over the last decade or so, Mitinori Saitou, a developmental biologist at Kyoto University, has led and participated in the most groundbreaking research in the field of in vitro gametogenesis, as the creation of artificial egg and sperm cells in the lab is formally known. If we can find a way to do it safely, the use of artificial sex cells could transform reproduction even more radically, and potentially redefine what it means to be a biological parent.īut that is a big “if.” Recipes for sperm and eggs Optimists might argue that the same concerns were originally raised about in vitro fertilization these days, around 73,000 babies are born each year as a result of assisted reproduction technologies like IVF in the US alone. And without that knowledge, lab-made egg and sperm cells could carry risks of devastating diseases that might not become evident until the resulting babies are born, or even later in their lives. In many ways, it’s still a deep mystery how sperm and eggs form. At the start of the game, three will be available, and each time a player dies, a new one is added.The big question is whether we’ll ever be able to turn promising lab results into acceptable and safe changes in how we reproduce. With aspects equipped, players can't unlock new boss cells or complete flawless boss achievements, forcing the most advanced players to stay away from them. However, there is a catch for those seeking true completion of the game. The other significant addition to Dead Cells to help push players further along comes is the group of 13 optional, overpowered buffs called 'aspects.' By speaking to the man to the left of the tailor, players can choose to take one aspect with them per run. This can give players the tools to take their skills to the next level, with whatever loadout they choose.

This feature allows instant access to these enemies and offers a quick way to gain experience on the furthest biomes. The second will allow players to practice against each discovered boss in their biome. The first allows players to fight individual enemies they've seen, or biome presets that focus on the game's average interactions. Once players are ready to fight, they can choose between two areas.
