1 00:00:20,890 --> 00:00:25,050 More than a hundred thousand people are on a waiting list right now for an organ transplant, and 2 00:00:25,050 --> 00:00:27,680 unfortunately that usually a one-to-one process. 3 00:00:27,680 --> 00:00:31,120 You get a organ when somebody else loses an organ. 4 00:00:31,120 --> 00:00:36,149 What if one day you could print your own organ, maybe from your own cells? 5 00:00:36,149 --> 00:00:39,480 Our goal is is that we're going to print a tissue that's more than a centimeter thick 6 00:00:39,480 --> 00:00:42,260 And you think a centimeter, that's not really that impressive. 7 00:00:42,260 --> 00:00:46,400 Well, that's more than 10 times what we can print on the ground, and we think that microgravity 8 00:00:46,400 --> 00:00:47,620 is going to be the key. 9 00:00:47,620 --> 00:00:51,150 This big L is actually the bioprinter, so this is the BFF. 10 00:00:51,150 --> 00:00:53,180 This actually legacy hardware. 11 00:00:53,180 --> 00:00:57,070 This is our ADSEP, or Advanced Space Experiment Processor. 12 00:00:57,070 --> 00:01:00,079 That's where we will put the tissue after it's printed. 13 00:01:00,079 --> 00:01:02,230 Basically, it's the maturation process. 14 00:01:02,230 --> 00:01:05,860 It's what turns a construct into a tissue because we're just putting building blocks 15 00:01:05,860 --> 00:01:09,110 down and then can step back and let biology do it biology does. 16 00:01:09,110 --> 00:01:12,630 As smart as we think we are biology will always be smarter. 17 00:01:12,630 --> 00:01:14,030 We're not just bringing back tissue. 18 00:01:14,030 --> 00:01:17,530 We're bringing back tissue that's cardiac tissue and it's going to beat just like a 19 00:01:17,530 --> 00:01:18,530 heart. 20 00:01:18,530 --> 00:01:19,810 That is cool as anything. 21 00:01:19,810 --> 00:01:24,540 So what happens if we build the next thing, and the next thing and the next thing eventually 22 00:01:24,540 --> 00:01:26,710 yeah, we're going to print a heart. 23 00:01:26,710 --> 00:01:28,409 That's really where we're going. 24 00:01:28,409 --> 00:01:34,840 Biorock is an experiment to study how microbes, bacteria interact with rocks in microgravity 25 00:01:34,840 --> 00:01:36,350 and simulated Martian gravity. 26 00:01:36,350 --> 00:01:40,960 And you might think why would we be interested in what microbes do in rocks? 27 00:01:40,960 --> 00:01:45,810 Well microbes on the Earth are used to break down rocks to release economically important 28 00:01:45,810 --> 00:01:46,810 elements. 29 00:01:46,810 --> 00:01:51,829 About 60% of the world's copper and gold is today extracted in Biomining. 30 00:01:51,829 --> 00:01:55,860 So the long-term future exploration of the Moon and Mars we might want to use microbes 31 00:01:55,860 --> 00:01:58,540 to help us break down rocks to do industry. 32 00:01:58,540 --> 00:02:03,250 That's a very long-term view in the shorter term view microbes break down rocks, turn 33 00:02:03,250 --> 00:02:04,399 them into soils. 34 00:02:04,399 --> 00:02:10,130 If we want to transform our lunar and Martian basalt into material that is more useful for 35 00:02:10,130 --> 00:02:13,980 agriculture for growing crops rather than having to take things with us we might use 36 00:02:13,980 --> 00:02:15,350 bacteria to do that. 37 00:02:15,350 --> 00:02:20,700 And then finally, of course we could use extraterrestrial materials to supply nutrients and life support 38 00:02:20,700 --> 00:02:21,700 systems. 39 00:02:21,700 --> 00:02:25,480 Why ship nutrients to the moon and Mars with all that mass and energy cost when you can 40 00:02:25,480 --> 00:02:30,150 just shovel in some lunar and Martian regolith into your life support system and provide 41 00:02:30,150 --> 00:02:32,340 the nutrients from that. 42 00:02:32,340 --> 00:02:37,360 Five to ten percent of fractures will not heal without extra help or intervention by 43 00:02:37,360 --> 00:02:39,099 the orthopedic surgeon. 44 00:02:39,099 --> 00:02:44,150 And what they use is a drug called bone morphogenetic protein and this helps to heal the bone. 45 00:02:44,150 --> 00:02:48,320 However, there is a risk of developing cancer with the use of these proteins. 46 00:02:48,320 --> 00:02:53,019 So identifying new bone-healing agents is really important and that's what we're testing 47 00:02:53,019 --> 00:02:54,019 here. 48 00:02:54,019 --> 00:02:55,880 So you may say well, why do we need to do that in spaceflight? 49 00:02:55,880 --> 00:02:58,360 Why can't we just do it here on Earth? 50 00:02:58,360 --> 00:03:02,660 Animals will walk immediately after you do a bone surgery. 51 00:03:02,660 --> 00:03:04,070 Humans, we don't. 52 00:03:04,070 --> 00:03:10,050 We use crutches, we may be bedridden, but in spaceflight the animals can't see that 53 00:03:10,050 --> 00:03:15,070 gravity and bone healing is helped when you walk, when you bear weight. 54 00:03:15,070 --> 00:03:20,180 And the drugs that we currently have work through that mechanism the drug we have patented 55 00:03:20,180 --> 00:03:24,401 does not, and so we think it will be better for bone healing and spaceflight if we go 56 00:03:24,401 --> 00:03:31,349 to Mars and have a fracture or here on Earth for the military personnel, for bad auto accidents 57 00:03:31,349 --> 00:03:36,440 and even for people with osteoporosis that have a fracture and it has impaired healing. 58 00:03:36,440 --> 00:03:40,620 This video here is showing the bioculture where the bioreactors will be residing and 59 00:03:40,620 --> 00:03:42,230 this has two compartments. 60 00:03:42,230 --> 00:03:47,700 One of them is a warm compartment at 37 degrees that's where the cells will grow and then 61 00:03:47,700 --> 00:03:52,739 the second compartment next to it is a cold compartment and that's where all the nutrients 62 00:03:52,739 --> 00:03:54,159 and the media will be in. 63 00:03:54,159 --> 00:03:58,799 And what happens is that crew member will inject the media at certain time points to 64 00:03:58,799 --> 00:04:02,230 feed these cells and then add the fixative at the end. 65 00:04:02,230 --> 00:04:07,909 The cells will come in back to the Earth and on Earth what we're going to do is isolate 66 00:04:07,909 --> 00:04:13,470 RNA and DNA and proteins from these cells and do whole genome analysis whole proteome 67 00:04:13,470 --> 00:04:18,609 and how metabolome analysis and this will help us understand the whole picture. 68 00:04:18,609 --> 00:04:24,130 We are taking advantage of a groundbreaking discovery that was made the almost a decade 69 00:04:24,130 --> 00:04:27,240 ago, which is the induced pluripotent stem cell technologies. 70 00:04:27,240 --> 00:04:33,900 So basically what it means is that we are now able to make in a laboratory stem cells 71 00:04:33,900 --> 00:04:40,100 starting from a little fill a little drop of blood from any of us or a little tiny piece 72 00:04:40,100 --> 00:04:46,289 of skin and we convert these cells into what we call induced pluripotent stem cells. 73 00:04:46,289 --> 00:04:49,700 We use them to generate any cell type that we want. 74 00:04:49,700 --> 00:04:53,979 So in our case that we're studying neurodegenerative diseases, we really want to make the brain 75 00:04:53,979 --> 00:04:55,469 cells and study them. 76 00:04:55,469 --> 00:04:59,719 Well have a cell line from a Parkinson's patient and also an age-matched control and these 77 00:04:59,719 --> 00:05:03,190 will be making dopaminergic neurons and these are the neurons that are lost in Parkinson's 78 00:05:03,190 --> 00:05:04,190 disease. 79 00:05:04,190 --> 00:05:10,250 And we will also have a cell line from a multiple sclerosis patient and these will be made into 80 00:05:10,250 --> 00:05:15,510 cortical neurons and microglia will be added to those and also in age-matched control. 81 00:05:15,510 --> 00:05:17,530 So we're interested to see what happens in space. 82 00:05:17,530 --> 00:05:20,390 Can we get more mature maturation of these cells? 83 00:05:20,390 --> 00:05:23,130 Can we make a better model for Parkinson's Disease and multiple sclerosis? 84 00:05:23,130 --> 00:05:29,890 So I think it has a lot of implications for the health of brain cells of astronauts who 85 00:05:29,890 --> 00:05:33,710 spend a lot of time in space, and we're also hoping to learn more about these two diseases
